Natural Lawn Care

Natural Lawn Care

Lawns do more than make your yard look good.
Lawns absorb water, which helps reduce storm runoff and improve water quality. Lawns also have a significant cooling effect, provide oxygen, trap dust and dirt, promote healthful micro-organisms, prevent erosion and filter rainwater contaminants.

Lawn care, however, has come at a high cost to the environment. According to the U.S. National Wildlife Federation:
# 30% of water used on the East Coast goes to watering lawns; 60% on the West Coast.
# 18% of municipal solid waste is composed of yard waste.
# The average suburban lawn received 10 times as much chemical pesticide per acre as farmland.
# Over 70 million tons of fertilizers and pesticides are applied to residential lawns and gardens annually. (Read Healthy lawns, healthy lungs)
# Per hour of operation, a gas lawn mower emits 10-12 times as much hydrocarbon as a typical auto. A weedeater emits 21 times more and a leaf blower 34 times more.
Where pesticides are used, 60 - 90% of earthworms are killed. Earthworms are important for soil health.
Much of the environmental cost associated with lawn care can be avoided.

Healthy Lawn Basics

The only way to reduce a dependence on chemical fertilizers is to develop a healthy lawn, which is naturally resistant to weeds, insects and diseases. If you need to fertilize your lawn more than once a year, consider these ways of improving the natural health of your lawn:

1. Improve the Soil
The first step is to test the soil's pH - it should read between 6.5 and 7.0, which is slightly acidic. Soil that is too acidic will need a sprinkling of lime; sulfur can be added to soil which is not acidic enough. You can buy a pH tester (see below, this page) for $40 - $60. Another solution is to have your soil tested professionally; first call your extension office - they often provide soil testing as a free service.
Lawns grow best in loamy soils that have a mix of clay, silt and sand. Too much clay in the soil mix, or heavy use, can compact the soil and prevent air and nutrient flow. Compacted soil may need aeration, a process of lifting small plugs of turf to create air spaces in the soil. For best results, rent an aerator or hire a lawn service to do the job - this will remove "finger size" plugs which improves aeration. Aeration is best done before top dressing and fertilizing.
Organic matter, such as compost and grass clippings, will benefit any type of soil; it lightens soil which is heavy in clay, and it builds humus in sandy soils, which helps retain water and nutrients.

2. Choose a Locally Adapted Grass
Grasses vary in the type of climate they prefer, the amount of water and nutrients required, shade tolerance and the degree of wear they can withstand. Ask your local garden center to recommend grass which is best adapted to your area.

The Modern Lawn Contributes to Climate Change

The Modern Lawn Contributes to Climate Change by Heather Havey, M.A.

http://www.naturalnews.com/026254.html

(NaturalNews) Americans love to have a healthy and beautiful yard. They have adopted and accepted a concept of beauty known as the "lawn." Many people believe that an expanse of short-trimmed grass-covered land is the most desirable look to have in one`s yard. This may include an occasional shrub or tree to add uniqueness and "diversity." Home-owners can help combat climate change by considering more diverse options for their own yards.

Yards can support green living and biological diversity, or yards can support climate change

In this time of global climate change, humans must consider the effects of all choices on the Earth. One`s yard offers an important opportunity to make a difference as an individual. So let`s ask the question: "Does my yard promote biological diversity as well as healthy water and soil and air?" Upon first consideration it may seem like everything is just fine. The reality is, however, that most people may not know the true, long-lasting effects of choices that have long been accepted as safe or healthy.

Climate change is real and is getting worse

Climate change has led to such phenomena as:
* a hotter and drier planet
* loss of forests, trees, plants, animals, and ground covers
* depletion of soil health and minerals from using chemicals, over-farming, and mowing
* loss of usable fresh water from both pollution and over-consumption
* drying out of the soil layers as water tables lower and rain patterns change
* loss of biological diversity including birds, bees, worms, insects, and much more
* mass extinction of many of Earth`s species - forever
* storm patterns and fires increasing in number and intensity

Some prevalent causes of climate change include:
* unsustainable production processes
* unsustainable and inhumane agricultural practices
* unconscious and wasteful consumption habits
* unchecked use of and dependence on fossil fuels
* unquestioned use of pesticides, herbicides, fungicides, and insecticides
* unquestioned use of chemical cleansers and other chemicals
* rapid and rampant deforestation (including in individual`s lawns and developing neighborhoods)

Each individual impacts the overall world balance. Every individual choice tips the balance in favor of Earth health or Earth destruction. This includes diet, transportation, use of resources, recycling, and so on. A big factor on this list also is one`s yard.

The "lawn" as we know it is unsustainable and harmful

An expanse of lawn can be lovely. However, its maintenance encourages pollutive practices:
* weekly mowing
* periodic chemical application of pesticides or fertilizers
* regular watering
* removal of trees or shrubs that may hinder ability to mow

Also, the lawn has long-term effects that encourage climate change and global warming. The lawn:
* dries out the topsoil layers, which also dries out the grass
* does not hold in water or coolness well
* space taken by grass prevents trees, shrubs, flowers, fruits and vegetables that would hold in moisture, re-mineralize the soil, and support birds, bees, and other life
* prevents sufficient biological diversity because there is no habitat for life to live in
* kills biological diversity because chemicals are designed to kill, and they do not know when to stop killing.

The overall effect of this is the transformation of Earth from a lush, diverse, abundant ground cover that protects and sustains us into a dried-out, burned-out, chemically-maintained, wildlife-killing wasteland. This look is currently seen as desirable and "beautiful." This "lawn" concept is promoting a hot, burned-out, poisoned world that lacks biological diversity.

Lawn is only one concept of beauty; there are many others that are lovelier and more sustainable.

There are incredible, beautiful alternatives to the modern "lawn."

One possibility is to fill one`s yard with trees, shrubs, flowers, plants, and trees. Choose local and native species that thrive in the conditions of the area. This will limit the need for maintenance or watering. Chemicals are unnecessary if plants are chosen well. A diverse yard like this will encourage many more birds, butterflies, bees, and other beneficial insects and animals.

Another option in addition is to grow food-bearing trees, shrubs, and plants in your yard. Combine flower beds with fruit trees and vegetable beds. Blueberry, raspberry, and blackberry bushes grow well in quite a few regions. Also in every region certain nut trees and fruit trees will grow well. Grape vines look lovely draped around a terraced porch. Many plants can even be grown in decorative pots. Pepper plants, for example, grow very well and produce many peppers. They look very lovely even inside your home.

A third way to help the Earth is to put bird houses and bathhouses among the trees. Feed birds organic birdseed. Grow sunflowers, which are lovely and produce many sunflower seeds for oneself and the birds.

Also buy eggs from a local farmer who raises them in a healthy and humane fashion. This choice ensures that one does not support animal torture or encourage development of new strains of bird flus, whose source have been linked in the past to inhumane mass farming practices.

Buy honey from local beekeepers. The bees suffer en masse from colony collapse disorder, which has been linked to both a mite and also the use of pesticides. All honeybees may soon go extinct if we do not protect them. Build a bee box and raise bees at home.

Collect food remains, mix them with soil and leaves and paper, let them decay, and spread these around the yard.

Other simple, helpful choices can include:
* plant trees every week
* plant every avocado, citrus, fruit, or nut seed from eaten foods
* give living gifts (plants and trees)
* become a guerrilla gardener (randomly plant flowers and trees in places, to help Earth and spread beauty).

What are the advantages of filling one`s yard with trees, plants, shrubs, bird houses, bathhouses, and bee boxes?

Some of many advantages include:
* Beauty
* Create protective habitat to protect dwindling bird, butterfly, bee, insect populations
* Promote wildlife diversity and survival
* Trees and plants hold in the moisture
* Trees and plants cool down the land
* Watering will be less needed
* Chemical applications will be unneeded
* Fertilizers will be unneeded
* Trees help soil to retain rain water as ground water, allowing it to linger longer in the soil for plants
* Cooling and moisturizing one`s own yard helps to counteract the devastating heating and drying of the Earth that is happening as we remove its groundcovers

Pesticides and herbicides are familiar but are not necessary

Do not trust chemicals. They were not used throughout history until the 20th century. They have an occasional beneficial need but for the most part they are simply unnecessary. Beyond this, they are very harmful. The famous bumper sticker says, "Pesticides are designed to kill, and they do not know when to stop killing."

Eat, farm, garden, and live organically.

One final choice that will greatly benefit Earth and one`s own health is the non-negotiable adoption of a natural, chemical-free lifestyle. Chemicals, again, are simply unnecessary. Nature provides everything that humans and animals need for health and well-being. Education and healthy choices are the keys.

Final thought

As our nation develops, our country is being covered by homes as well as shopping centers, business districts, and road systems. The world once was totally covered with trees, wild ground covers, and endless diverse forms of wildlife. People are removing nearly all of it through "development." The world humans are creating is the world that we see in all of our yards. At this moment, this means: very little diversity, nutrient-poor soil, no insects, virtually no habitat for birds or other animals, and an abundance of pesticide, herbicide, and chemical fertilizer. This does not provide us with oxygen, food, moist soils, moisture in the air, coolness from trees, biological diversity, health, or as much beauty. It leaves our Earth much hotter, drier, and exposed to potential further harm. There is very little room for sustainability, thriving of life on Earth, or a healthy future in what Americans currently prefer as "the perfect lawn."

The choice to transform the lawn into a vibrant, diverse, food-bearing, life-supporting garden is a choice that adds beauty, helps Earth, and helps each family. These choices honor the diversity, strength, and healing nature of Earth.

I'm always struck when I travel outside the United States how rare it is to see large expanses of lawn in residential areas in most other countries. Americans are truly grass crazy. We're downright sod-o-maniacs, you might say.
grass

But our dandelion-free, putting green-perfect lawns are tough on the environment and tough on our wallets. Between the water they require, the pesticides and fertilizers, and pollutant spewing, four-cycle lawnmowers, our lawns really aren't as green as they look.

And with U.S. lawn care services now a $12 billion annual industry, our lawns are cutting a lot of the green out of our bank accounts as well. Basic lawn-care service averages about $120-$150 per month, which could easily be an expense of $1,000 a year or more depending on where you live and the length of the growing season.

Author Michael Pollan wrote, "A lawn is nature under totalitarian rule." Down with the dictator!, I say. Why not reduce the size of your lawn this summer -- or even eliminate it entirely -- and save money, time and the environment too?

Simple Ways To Afford Your Green Lifestyle! - by Heather Havey, M.A.

Simple Ways to Afford Your Green Lifestyle! - by Heather Havey, M.A.

The economy may be challenged, and our own wallets may also be challenged, during these times. However, we still would like to eat right. It is more important than simply a desire to eat well; it is a non-negotiable. It is your Life we are talking about!

That said, the NUMBER ONE excuse that I hear from people is that they "can't afford to eat healthy." I have a few responses to this that I hope will really help us all!

So you understand where I am coming from: We are all in this together, and I feel your pain. I live as a monk, a very simple lifestyle with very few possessions and low income, and I understand the challenges that can be presented for our wallets in this endeavor towards healthy, holy living. But, we can do it! Here are some helpful tips...

(1) Pay now, or pay later! You can pay a little more now for organic produce and natural foods lifestyle, or you will pay later in feeling tired, feeling bad, and having high medical bill potentials.

(2) Buy local, from farmers...or grow your own organic vegetables/fruits. Local farmers are going to charge you significantly less for their products than you would pay in a grocery store, health food store, or coop. So seek out your local organic farmers, CSA farms (Community Supported Agriculture), and so on. Another option is to grow your own organic vegetable garden. Local foods do not have to be shipped cross country or around the world, so they can be sold to you much cheaper. It is okay to choose local produce that does not have organic certification, as long as they grew them "unsprayed" (without applying pesticides).

(3) Plant fruit and nut trees all over your property. Not only will this make the birds and squirrels happy, but trees protect smaller shrubs and crops from harsh weather conditions, and provide healthy habitat for many types of life. Also, you will get hundreds of fruits each year off of every single healthy tree. Planting trees helps not only your and your family, helps not only the animals and plants, but it also helps the world to combat greenhouse gases and global warming! Trees release more Oxygen into the atmosphere, and we are clear-cutting the entire planet right now. WE DESPERATELY NEED TREES! And they will lower your grocery bills! If you have enough trees, you could even sell your fruits and nuts locally, and MAKE money off your trees.

(4) Buy bulk! Bulk bins make items SO much more affordable, and they give us the double benefit of saving on packaging materials and plastic bags. Many, many items - ranging from cereals, beans, grains, chocolates and desserts, herbs, spices, honey, nut butters, and even household items like soaps, shampoos, and cleaning products are available at health food stores in bulk bins.

(5) Eat Natural Foods. Though organic foods may SEEM expensive, really they are a much better deal than conventional produce. The reason for this is that they are far higher in nutritional value than conventional produce, so you get far more nutrition for your penny. Also, they have no poisons within them, so they are not filling your muscle tissues with small amounts of poison that build up over time to break down your health. Also, the most expensive food choices out there tend to be the most highly processed, and least healthy, ones. So when you go shopping, simply choose the most natural, whole, raw, and organic choices that you can.
Some ideas include eating fruit salad, vegetable salads, smoothies, juices, and sandwiches or wraps that you make yourself at home. These options are endless, are all natural, support your own health and the health of the planet, and cost less overall. Meat and dairy are the most expensive choices out there that you can make.

(6) Adopt a vegetarian or vegan diet. Diet is a personal choice that everyone must make, but veg choices are the healthiest and the most afforable choices out there.

(7) Grow your own food. It is actually very easy to grow food. It does not take much time after you set things up. All you really need is a small pot or seed sprouting tray, some basic soil, a little soil nutrient (organic fertilizer or compost or manure compost), seeds, and love. You can grow quite a few things indoors. Pepper plants (bell, or jalapeno, or other types) grow very beautifully and well indoors. So do most herbs and many other plants. I am currently even growing starfruit trees all over my room because it is too cold at nights for baby trees where I live right now. Plants need sunlight, water every few days, nutrients occasionally, and love. With half an acre of land, you could grow enough food for six families or more. A little land, and a little love for it, can go a LONG way. To get started, get some organic or heirloom seeds from Seeds of Change.

(8) Prepare your food at home rather than eating out. You will save a lot of money doing this - on gas, on tips, on restaurant food costs, and so on. It is easy, it is fun, and it is a wonderful bonding experience to either cook for your family/friends or cook with your family/friends.

(9) Bring your lunch to work/school rather than eating out there. You can ensure that you eat much more healthy choices this way, and it will cost you far less than it would to eat out everyday at work or school.

(10) Live simply, and eat simply. The more simple the meals you make, the less they will cost. Also, simpler meals tend to be healthier meals. The simplest and easiest lifestyle, and one of the world's healthiest, is to be an organic raw foodist grazer. This means that you eat only raw, organic fruits, vegetables, nuts, seeds, and grains, and you simply snack on items whenever you feel like it. Your body will become cleaner and healthier, you will feel more energy, and you will lose weight if you need to. You will feel great. Simplicity and quality are the keys.

(11) Love, Love, Love. This is the answer for everything: for your own body and health, for the plants and trees and wildlife, for our friends and family, for the soil, for the entire world. The more we live with love and regard for others in our hearts, the happier and healthier our worlds will be. And best news yet! Love is totally free and an unlimited resource.

Aloha, have a blessed day, Heather Havey

Please send ecards to your friends and family.

Learning and Living Organic Lifestyle with WWOOF

source: Learning and Living Organic Lifestyle with WWOOF

(NaturalNews) Since 1971, people are living and learning sustainable lifestyles thanks in part to WWOOF - World Wide Opportunities on Organic Farms. Founded by Sue Croppard, WWOOF was created with the goal of giving city dwellers a weekend opportunity to re-connect with nature and support organic agriculture.

WWOOF organizations publish listings of organic farms and gardens that host volunteers - providing food, housing, and in-field education in exchange for help from the volunteers. WWOOF has now become an international movement across six continents and more than fifty countries with programs ranging from weekends to seasonal and year-long stays.

Sue Croppard, founder of WWOOF, intends that through WWOOF people can get first hand experience of organic farming, give assistance to organic farmers, get into the countryside, strengthen the organic movement, form links between city and rural dwellers, and "facilitate inter-cultural understanding between people of different nationalities".

WWOOF is used by many to live sustainable lifestyles; living on a self-sufficient farm allows someone to live without driving and paying for food that was shipped from hundreds if not thousands of miles a way.

Wwoofing is also a method for low-cost traveling - since it is a volunteer arrangement, a person does not need a visa to work in a foreign country. Staying at hotels and hostels can be very expensive especially for long periods of time.

Also, those who wish to work in environmental advocacy may have trouble finding adequate work that pays enough for city-life. Through work-stay programs individuals do not have to concern themselves with rent, food, and may even improve their health through the hours of exercise under the sun.

What does Wwoofing look like?

There are over seven hundred farms affiliated with WWOOF in the USA alone and hundreds more in the world. The WWOOF listing contains wide diversity in location and farm type. If one wants to make sure they get the food they want, it is good to work at the farm that grows it.

There are farms that demand strict vegetarianism and grow nearly all their own food and there are also farms that focus on raising cattle or sheep for meat and purchase and trade for the rest of their diet with other local farmers.

Charan Springs Farm in Cambria, California grows lettuce, broccoli, brussel sprouts, mushrooms, watercress, tangelos, blood-oranges, chard, and five varieties of avocados. Charan Springs also offers medicinal hot springs. There are typically around a dozen people staying at Charan Springs.

Some farms in the tropical regions such as Hawaii and Costa Rica offer housing and organic food in exchange for as little as sixteen hours per week of work. Wwoofers are not paid for their time, but the cost might be profitable to some to eat a purely organic diet and live on a fifty acre ranch a stone`s throw from the Pacific Ocean.

Rebekah, a "wwoofer" at One Love Gardens, a farm on the Big Island of Hawaii said:

"The simplicity of life at `One Love` was brilliant: bathing in the fresh mountain stream and eating almost only what we grew, turns me on to a blessed and sacred way of being. To know that this way of life is still possible and is happening, in our crazy 21st century world opened the doors of my mind."

However, not all organic farms sound like vacations and expectations of the exchange are made clear before a person comes to volunteer. While wwoofers may work a four day sixteen hour work week on the Big Island... at a bio-dynamic farm near Grass Valley, California wwoofers are expected to wake before dawn to work fifty hours a week.

Another farm called Heaven and Earth Farm in Nevada County, California offers organic food, housing which consists of a trailer or tent, and a $50 a week stipend in exchange for forty hours of work per week. The specifics are made clear in the WWOOF guide.

What can people learn with WWOOF?

Educational opportunities vary from farm to farm and depend on season and length of stay. If one comes to a farm during harvest time the work might be limited to picking fruit or preparing vegetables to take to market. However there are many different activities that go on at any given farm.

Food preserving, planting, marketing, community living, green construction, alternative energy, animal husbandry, and permaculture are just some of the skills wwoofers can learn.

Heated in Aprovecho

"A great experience, but it can get dirty," said Elizabeth M. of Dayton Ohio, having wwoofed throughout California and Oregon. "It can be like any other co-housing situation with conflicts and house meetings, sometimes things got pretty heated in Aprovecho". Aprovecho, in Cottage Grove, Oregon, practices sustainable forestry and researches furnace design.

For some, wwoofing creates space for meditation and work on personal growth; much of the farm-work such as weeding by hand can be done by a single individual, so the farmer may instruct the wwoofer where to work and leave to work somewhere else at the same time.

"These are the survival skills of pioneers"

Says Verona Bass of her UK wwoofing experience: "Some of the most satisfying moments are when I can do lateral thinking to solve practical problems, to use 'logistics'. Sometimes the right tool is lacking, or a wheelbarrow can't go over the terrain but some sort of dragging device will work better. I think these are the survival skills of pioneers, and we may yet need to become more inventive to re-use what we have available but in altered ways."

Bass continues, "Wwoofing slows me down. I engage with the moment in a way not easily achieved anywhere else. When I've been working with my head down, and I straighten up for a while, looking over a long quiet view of hills, fields, a loch, or an estuary, I breathe in and feel privileged."

10 Reasons Why Organic Can Feed The World

10 reasons why organic can feed the world
Ed Hamer & Mark Anslow 01/03/2008

source: http://www.theecologist.org/pages/archive_detail.asp?content_id=1184

Can organic farming feed the world? Ed Hamer and Mark Anslow say yes, but we must farm and eat differently

1. Yield

Switching to organic farming would have different effects according to where in the world you live and how you currently farm.

Studies show that the less-industrialised world stands to benefit the most. In southern Brazil, maize and wheat yields doubled on farms that changed to green manures and nitrogenfixing leguminous vegetables instead of chemical fertilisers.1 In Mexico, coffee-growers who chose to move to fully organic production methods saw increases of 50 per cent in the weight of beans they harvested. In fact, in an analysis of more than 286 organic conversions in 57 countries, the average yield increase was found to be an impressive 64 per cent.2

The situation is more complex in the industrialised world, where farms are large, intensive facilities, and opinions are divided on how organic yields would compare.

Research by the University of Essex in 1999 found that, although yields on US farms that converted to organic initially dropped by between 10 and 15 per cent, they soon recovered, and the farms became more productive than their all-chemical counterparts.3 In the UK, however, a study by the Elm Farm Research Centre predicted that a national transition to all-organic farming would see cereal, rapeseed and sugar beet yields fall by between 30 and 60 per cent.4 Even the Soil Association admits that, on average in the UK, organic yields are 30 per cent lower than non-organic.

So can we hope to feed ourselves organically in the British Isles and Northern Europe? An analysis by former Ecologist editor Simon Fairlie in The Land journal suggests that we can, but only if we are prepared to rethink our diet and farming practices.5 In Fairlie’s scenario, each of the UK’s 60 million citizens could have organic cereals, potatoes, sugar, vegetables and fruit, fish, pork, chicken and beef, as well as wool and flax for clothes and biomass crops for heating. To achieve this we’d each have to cut down to around 230g of beef (½lb), compared to an average of 630g (1½lb) today, 252g of pork/bacon, 210g of chicken and just under 4kg (9lb) of dairy produce each week – considerably more than the country enjoyed in 1945. We would probably need to supplement our diet with homegrown vegetables, save our food scraps as livestock feed and reform the sewage system to use our waste as an organic fertiliser.

2. Energy

Currently, we use around 10 calories of fossil energy to produce one calorie of food energy. In a fuel-scarce future, which experts think could arrive as early as 2012, such numbers simply won’t stack up. Studies by the Department for Environment, Food and Rural affairs over the past three years have shown that, on average, organically grown crops use 25 per cent less energy than their chemical cousins. Certain crops achieve even better reductions,including organic leeks (58 per cent less energy) and broccoli (49 per cent less energy). When these savings are combined with stringent energy conservation and local distribution and consumption (such as organic box schemes), energy-use dwindles to a fraction of that needed for an intensive, centralised food system. A study by the University of Surrey shows that food from Tolhurst Organic Produce, a smallholding in Berkshire, which supplies 400 households with vegetable boxes, uses 90 per cent less energy than if non-organic produce had been delivered and bought in a supermarket.

Far from being simply ‘energy-lite’, however, organic farms have the potential to become self-sufficient in energy – or even to become energy exporters. The ‘Dream Farm’ model, first proposed by Mauritius-born agroscientist George Chan, sees farms feeding manure and waste from livestock and crops into biodigesters, which convert it into a methane-rich gas to be used for creating heat and electricity. The residue from these biodigesters is a crumbly, nutrient-rich fertiliser, which can be spread on soil to increase crop yields or further digested by algae and used as a fish or animal feed.

3. Greenhouse gas emissions and climate change

Despite organic farming’s low-energy methods, it is not in reducing demand for power that the techniques stand to make the biggest savings in greenhouse gas emissions.

The production of ammonium nitrate fertiliser, which is indispensable to conventional farming, produces vast quantities of nitrous oxide – a greenhouse gas with a global warming potential some 320 times greater than that of CO2. In fact, the production of one tonne of ammonium nitrate creates 6.7 tonnes of greenhouse gases (CO²e), and was responsible for around 10 per cent of all industrial greenhouse gas emissions in Europe in 2003.6

The techniques used in organic agriculture to enhance soil fertility in turn encourage crops to develop deeper roots, which increase the amount of organic matter in the soil, locking up carbon underground and keeping it out of the atmosphere. The opposite happens in conventional farming: high quantities of artificially supplied nutrients encourage quick growth and shallow roots. A study published in 1995 in the journal Ecological Applications found that levels of carbon in the soils of organic farms in California were as much as 28 per cent higher as a result.7 And research by the Rodale Institute shows that if the US were to convert all its corn and soybean fields to organic methods, the amount of carbon that could be stored in the soil would equal 73 per cent of the country’s (would-be) Kyoto targets for CO² reduction.8

Organic farming might also go some way towards salvaging the reputation of the cow, demonised in 2007 as a major source of methane at both ends of its digestive tract. There’s no doubt that this is a problem: estimates put global methane emissions from ruminant livestock at around 80 million tonnes a year,9 equivalent to around two billion tonnes of CO²,10 or close to the annual CO² output of Russia and the UK combined.11 But by changing the pasturage on which animals graze to legumes such as clover or birdsfoot trefoil (often grown anyway by organic farmers to improve soil nitrogen content), scientists at the Institute of Grassland and Environmental Research believe that methane emissions could be cut dramatically. Because the leguminous foliage is more digestible, bacteria in the cow’s gut are less able to turn the fodder into methane. Cows also seem naturally to prefer eating birdsfoot trefoil to ordinary grass.

4. Water use

Agriculture is officially the most thirsty industry on the planet, consuming a staggering 72 per cent of all global freshwater at a time when the UN says 80 per cent of our water supplies are being overexploited.12,13

This hasn’t always been the case. Traditionally, agricultural crops were restricted to those areas best suited to their physiology, with drought-tolerant species grown in the tropics and water-demanding crops in temperate regions.14 Global trade throughout the second half of the last century led to a worldwide production of grains dominated by a handful of high-yielding cereal crops, notably wheat, maize and rice. These thirsty cereals – the ‘big three’ – now account for more than half of the world’s plant-based calories and 85 per cent of total grain production.15

Organic agriculture is different. Due to its emphasis on healthy soil structure, organic farming avoids many of the problems associated with compaction, erosion, salinisation and soil degradation, which are prevalent in intensive systems.16 Organic manures and green mulches are applied even before the crop is sown, leading to a process known as ‘mineralisation’ – literally the fixing of minerals in the soil. Mineralised organic matter, conspicuously absent from synthetic fertilisers, is one of the essential ingredients required physically and chemically to hold water on the land.

Organic management also uses crop rotations, undersowing and mixed cropping to provide the soil with near-continuous cover. By contrast, conventional farm soils may be left uncovered for extended periods prior to sowing, and again following the harvest, leaving essential organic matter fully exposed to erosion by rain, wind and sunlight. In the US, a 25-year Rodale Institute experiment on climatic extremes found that, due to improved soil structure, organic systems consistently achieve higher yields during periods both of drought and flooding.17

5. Localisation

The globalisation of our food supply, which gives us Peruvian apples in June and Spanish lettuces in February, has seen our food reduced to a commodity in an increasingly volatile global marketplace. Although year-round availability makes for good marketing in the eyes of the biggest retailers, the costs to the environment are immense.

Friends of the Earth estimates that the average meal in the UK travels 1,000 miles from plot to plate.18 In 2005, Defra released a comprehensive report on food miles in the UK, which valued the direct environmental, social and economic costs of food transport in Britain at £9 billion each year. In addition, food transport accounted for more than 30 billion vehicle kilometres, 25 per cent of all HGV journeys and 19 million tonnes of carbon dioxide emissions in 2002 alone.19

The organic movement was born out of a commitment to provide local food for local people, and so it is logical that organic marketing encourages localisation through veg boxes, farm shops and stalls. Between 2005 and 2006, organic sales made through direct marketing outlets such as these increased by 53 per cent, from £95 to £146 million, more than double the sales growth experienced by the major supermarkets.20 As we enter an age of unprecedented food insecurity, it is essential that our consumption reflects not only what is desirable, but also what is ultimately sustainable. While the ‘organic’ label itself may inevitably be hijacked, ‘organic and local’ represents a solution with which the global players can simply never compete.

6. Pesticides

It is a shocking testimony to the power of the agrochemical industry that in the 45 years since Rachel Carson published her pesticide warning Silent Spring, the number of commercially available synthetic pesticides has risen from 22 to more than 450.21

According to the World Health Organization there are an estimated 20,000 accidental deaths worldwide each year from pesticide exposure and poisoning.22 More than 31 million kilograms of pesticide were applied to UK crops alone in 2005, 0.5 kilograms for every person in the country.23 A spiralling dependence on pesticides throughout recent decades has resulted in a catalogue of repercussions, including pest resistance, disease susceptibility, loss of natural biological controls and reduced nutrient-cycling.24

Organic farmers, on the other hand, believe that a healthy plant grown in a healthy soil will ultimately be more resistant to pest damage. Organic systems encourage a variety of natural methods to enhance soil and plant health, in turn reducing incidences of pests, weeds and disease.

First and foremost, because organic plants grow comparatively slower than conventional varieties they have thicker cell walls, which provide a tougher natural barrier to pests. Rotations or ‘break-crops’, which are central to organic production, also provide a physical obstacle to pest and disease lifecycles by removing crops from a given plot for extended periods.25 Organic systems also rely heavily on a rich agro-ecosystem in which many agricultural pests can be controlled by their natural predators.

Inevitably, however, there are times when pestilence attacks are especially prolonged or virulent, and here permitted pesticides may be used. The use of organic pesticides is heavily regulated and the International Federation of Organic Agriculture Movements (IFOAM) requires specific criteria to be met before pesticide applications can be justified.26

There are in fact only four active ingredients permitted for use on organic crops: copper fungicides, restricted largely to potatoes and occasionally orchards; sulphur, used to control additional elements of fungal diseases; Retenone, a naturally occurring plant extract, and soft soap, derived from potassium soap and used to control aphids. Herbicides are entirely prohibited.

7. Ecosystem impact

Farmland accounts for 70 per cent of UK land mass, making it the single most influential enterprise affecting our wildlife.27 Incentives offered for intensification under the Common Agricultural Policy are largely responsible for negative ecosystem impacts over recent years. Since 1962, farmland bird numbers have declined by an average of 30 per cent. During the same period more than 192,000 kilometres of hedgerows have been removed, while 45 per cent of our ancient woodland has been converted to cropland.28

By contrast, organic farms actively encourage biodiversity in order to maintain soil fertility and aid natural pest control. Mixed farming systems ensure that a diversity of food and nesting sites are available throughout the year, compared with conventional farms where autumn sow crops leave little winter vegetation available.29

Organic production systems are designed to respect the balance observed in our natural ecosystems. It is widely accepted that controlling or suppressing one element of wildlife, even if it is a pest, will have unpredictable impacts on the rest of the food chain. Instead, organic producers regard a healthy ecosystem as essential to a healthy farm, rather than a barrier to production.

In 2005, a report by English Nature and the RSPB on the impacts of organic farming on biodiversity reviewed more than 70 independent studies of flora, invertebrates, birds and mammals within organic and conventional farming systems. It concluded that biodiversity is enhanced at every level of the food chain under organic management practices, from soil micro-biota right through to farmland birds and the largest mammals.30

8. Nutritional benefits

While an all-organic farming system might mean we’d have to make do with slightly less food than we’re used to, research shows that we can rest assured it would be better for us.

In 2001, a study in the Journal of Complementary Medicine found that organic crops contained higher levels of 21 essential nutrients than their conventionally grown counterparts, including iron, magnesium, phosphorus and vitamin C. The organic crops also contained lower levels of nitrates, which can be toxic to the body.31

Other studies have found significantly higher levels of vitamins – as well as polyphenols and antioxidants – in organic fruit and veg, all of which are thought to play a role in cancer-prevention within the body.32

Scientists have also been able to work out why organic farming produces more nutritious food. Avoiding chemical fertiliser reduces nitrates levels in the food; better quality soil increases the availability of trace minerals, and reduced levels of pesticides mean that the plants’ own immune systems grow stronger, producing higher levels ofantioxidants. Slower rates of growth also mean that organic food frequently contains higher levels of dry mass, meaning that fruit and vegetables are less pumped up with water and so contain more nutrients by weight than intensively grown crops do.33

Milk from organically fed cows has been found to contain higher levels of nutrients in six separate studies, including omega-3 fatty acids, vitamin E, and beta-carotene, all of which can help prevent cancer. One experiment discovered that levels of omega-3 in organic milk were on average 68 per cent higher than in non-organic alternatives.34

But as well as giving us more of what we do need, organic food can help to give us less of what we don’t. In 2000, the UN Food and Agriculture Organization (FAO) found that organically produced food had ‘lower levels of pesticide and veterinary drug residues’ than non-organic did.35 Although organic farmers are allowed to use antibiotics when absolutely necessary to treat disease, the routine use of the drugs in animal feed – common on intensive livestock farms – is forbidden. This means a shift to organic livestock farming could help tackle problems such as the emergence of antibiotic-resistant bacteria.

9. Seed-saving

Seeds are not simply a source of food; they are living testimony to more than 10,000 years of agricultural domestication. Tragically, however, they are a resource that has suffered unprecedented neglect. The UN FAO estimates that 75 per cent of the genetic diversity of agricultural crops has been lost over the past 100 years.36

Traditionally, farming communities have saved seeds year-on-year, both in order to save costs and to trade with their neighbours. As a result, seed varieties evolved in response to local climatic and seasonal conditions, leading to a wide variety of fruiting times, seed size, appearance and flavour. More importantly, this meant a constant updating process for the seed’s genetic resistance to changing climatic conditions, new pests and diseases.

By contrast, modern intensive agriculture depends on relatively few crops – only about 150 species are cultivated on any significant scale worldwide. This is the inheritance of the Green Revolution, which in the late 1950s perfected varieties Filial 1, or F1 seed technology, which produced hybrid seeds with specifically desirable genetic qualities.37 These new high-yield seeds were widely adopted, but because the genetic makeup of hybrid F1 seeds becomes diluted following the first harvest, the manufacturers ensured that farmers return for more seed year on year.

With its emphasis on diversity, organic farming is somewhat cushioned from exploitation on this scale, but even Syngenta, the world’s third-largest biotech company, now offers organic seed lines. Although seedsaving is not a prerequisite for organic production, the holistic nature of organics lends itself well to conserving seed.

In support of this, the Heritage Seed Library, in Warwickshire, is a collection of more than 800 open-pollinated organic varieties, which have been carefully preserved by gardeners across the country. Although their seeds are not yet commercially available, the Library is at the forefront of addressing the alarming erosion of our agricultural diversity.

Seed-saving and the development of local varieties must become a key component of organic farming, giving crops the potential to evolve in response to what could be rapidly changing climatic conditions. This will help agriculture keeps pace with climate change in the field, rather than in the laboratory.

10. Job creation

There is no doubt British farming is currently in crisis. With an average of 37 farmers leaving the land every day, there are now more prisoners behind bars in the UK than there are farmers in the fields.38

Although it has been slow, the decline in the rural labour force is a predictable consequence of the industrialisation of agriculture. A mere one per cent of the UK workforce is now employed in land-related enterprises, compared with 35 per cent at the turn of the last century.39

The implications of this decline are serious. A skilled agricultural workforce will be essential in order to maintain food security in the coming transition towards a new model of post-fossil fuel farming. Many of these skills have already been eroded through mechanisation and a move towards more specialised and intensive production systems.

Organic farming is an exception to these trends. By its nature, organic production relies on labour-intensive management practices. Smaller, more diverse farming systems require a level of husbandry that is simply uneconomical at any other scale. Organic crops and livestock also demand specialist knowledge and regular monitoring in the absence of agrochemical controls.

According to a 2006 report by the University of Essex, organic farming in the UK provides 32 per cent more jobs per farm than comparable non-organic farms. Interestingly, the report also concluded that the higher employment observed could not be replicated in non-organic farming through initiatives such as local marketing. Instead, the majority (81 per cent) of total employment on organic farms was created by the organic production system itself. The report estimates that 93,000 new jobs would be created if all farming in the UK were to convert to organic.

Organic farming also accounts for more younger employees than any other sector in the industry. The average age of conventional UK farmers is now 56, yet organic farms increasingly attract a younger more enthusiastic workforce, people who view organics as the future of food production. It is for this next generation of farmers that Organic Futures, a campaign group set up by the Soil Association in 2007, is striving to provide a platform.

Why Organic Lawn Care is the Right Choice

source: www.eco-gardeners.com

I recently came across an excellent study conducted by Environment & Human Health, Inc., a nonprofit organization dedicated to promoting public education concerning the relationships between the environment and human health.

“Risks from Lawn Care Pesticides” is a comprehensive study full of interesting and useful information and definitely worth the read. Topics include health and ecological effects of pesticides and they also include lists of specific products and ingredients that are highly toxic and harmful to children, pets and the water supply.

Some interesting findings include:
• The U.S. Fish and Wildlife Service reported that “homeowners use up to 10 times more chemical pesticides per acre on their lawns than farmers use on crops.”
• Pesticides are intentionally toxic substances. Some chemicals commonly used on lawns and gardens have been associated with birth defects, mutations, adverse reproductive effects, and cancer in laboratory animals.
• Children, infants, and fetuses may be especially vulnerable to the health effects of pesticides before the age of five, when their cells are normally reproducing most rapidly.
• EPA has tested only nine of 750 registered pesticides for their effects on the developing nervous system; six of the nine tested were more harmful to young animals than adults.
• The U.S. Geological Survey found that 96 percent of all fish analyzed in major rivers and streams contained residues of one or more pesticides at detectable levels.
• Pesticides have been identified as a potential cause of amphibian declines and deformities and have been implicated as one of the reasons that wild and managed pollinators are disappearing at alarming rates.
• Homeowners may unknowingly contaminate their own well water by using pesticides on their lawns.
