Organic Farming Principles
Organic foods set the standard for top quality freshness,
texture, flavor, and variety. These foods are produced without the standard
array of modern toxic and persistent chemicals commonly used on conventional
food products since the 1950s. Yet organic farming isn't primitive, it's
actually farming with our future at heart.
Basic Conventional Farming
To help understand the differences, here is a quick look at conventional
farming practices. Conventional growers use an assortment of synthetic
pesticides, fertilizers, genetically engineered organisms and growth enhancers
to stimulate their soil and crops. Their focus is on short term yield
increases rather than long term soil health. When the soil is found lacking
in various nutrients, they are added through the use of synthetic fertilizers.
Crops may be grown from genetically engineered seeds. Pesticides or fungicides
may be used to control insects in crop storage and transportation. Conventional
farmers can use manure without restrictions and are not required to keep
records of their production practices.
Basic Organic Farming
Organic farmers manage their crops using proactive practices to prevent
problems. They strive to:
- Replenish and maintain soil fertility.
- Eliminate the use of toxic and persistent chemical
pesticides and fertilizers.
- Restore, maintain, and enhance ecological harmony.
- Build and support biologically diverse agriculture.
To be certified as organic, all organic farmers must
keep records verifying their practices and products used.
Organic Farming Practices
Organic farmers select the most environmentally friendly solutions to
the pests and disease problems which affect their crops.
These strategies include:
Crop rotation: This means alternating the crops grown
in each field, rather than growing the same crop year after year (mono-cropping).
Different plants contribute varying nutrients to the soil.
By rotating crops, the soil is naturally replenished. This time-honored
practice can eliminate the need for insecticides in many crops since the
insect's life cycle and habitat are interrupted and destroyed.
Cover crops: Cover crops can protect the soil, add nutrients,
prevent weed growth, aerate the soil with deep root systems, and fertilize
the soil by building organic matter when plowed under. Sometimes referred
to as "green manure crops," cover crops also conserve soil moisture and
feed the soil's microflora and fauna, such as earthworms. By encouraging
the lifecycles of beneficial soil organisms, problematic bacteria, fungi,
nematodes, diseases and insects are prevented from proliferating.
Release beneficial insects: Organic farmers utilize natural
predators to control pests that destroy their crops, which eliminates
the need for chemical insecticides that remains in the soil for years.
Add compost and plant wastes: Use of manure in organic
production (including raw animal manure) is highly regulated, unlike the
animal manures and fertilizers used in conventional farming. The continuous
cycling of naturally occurring materials helps the soil retain moisture
and nutrients. Correctly made compost kills pathogens and weed seeds,
producing a fertilizer that encourages soil life and healthy crops.
Organic Livestock Practices
A healthy environment for their animals is foremost for organic livestock
producers. Fresh air, clean water, outdoor access, proper housing and
100% organic feed all help reduce stress and keep the animals healthy.
This decreases the need for antibiotics, which are not allowed in animals
raised for their organic meat (some vaccines are allowed). If an animal
needs antibiotic treatment, then the animal is not allowed to be sold
as "organic." Other livestock practices include:
- No growth hormones or genetically engineered products.
- No animal by-products in feed.
- Cows and other ruminants must have access to pasture.
- Slaughtering practices must be humane.
- Manure must be managed to prevent contamination
of crops, soil or water by plant nutrients, pathogenic organisms, heavy
metals or residues of prohibited substances.
The National List of Allowed and Prohibited Substances
As part of the USDA Organic Rule, the National Organic Standards Board (NOSB)
established the National List of Allowed and Prohibited Substances. This
list contains synthetic substances that are allowed in organic farming and
production as well as a list of natural substances that are prohibited.
The NOSB reviews substances to be added or removed from the National List
on an ongoing basis. They recommend that all agricultural inputs be evaluated
for long-term effects on the environment, not simply on whether these inputs
are synthetic or natural. Their decisions are based on:
- Effect on human health.
- Effect on the farm eco-system.
- Toxicity and mode of action.
- Availability of gentler alternatives.
- Probability of environmental contamination during manufacture, use and
disposal.
- Potential for interactions with other materials used.
- Overall compatibility with a system of sustainable agriculture.
