This means no artificial fertilizers, chemical pesticides, herbicides, plant growth regulators or genetically modified organisms.
When tested on less than 10 acres, non-engineered bacteria and chemical pesticides are completely exempt from regulation.
Enhanced pest resistance in plants has obviated the need for hundreds of millions of pounds of chemical pesticides (and thereby reduced environmental and occupational exposures).
First, the cultivation of genetically engineered crops has drastically reduced the use of chemical pesticides, resulting in less runoff into waterways and ground water and fewer poisonings of farmers and their families.

Worried specifically about synthetic chemical pesticides?
FORBES: Bittman of the 'New York Times': Always Out To Lunch
Although such genetic engineering is essentially an extension, or refinement, of techniques that have been around for centuries, it has led to less use of chemical pesticides, a drop in pesticide poisoning of farmers and their families, more environment-friendly agronomic practices and greater profits for farmers.
FORBES: How Groundbreaking New Technologies Are Smothered By Anti-Technology Ideologues
This approach, which has been repeatedly condemned by the scientific community, has discouraged the development of new pest-resistant crops, encouraged greater use of synthetic chemical pesticides, and limited the use of the newest genetic engineering technology mainly to larger developers who can pay the inflated regulatory costs.
FORBES: EPA Biotech Regulation Bucks The Scientific Consensus
As that report predicted when the regulation was proposed more than a decade ago, it discourages the development of new pest-resistant crops and prolongs and increases the use of synthetic chemical pesticides, limits the use of the technology mainly to larger developers who can pay the inflated regulatory costs, and handicaps the U.S. in competition for international markets.
And, surprisingly, despite their rejection of most modern technologies, many of Mr Hostetler's neighbours quite like chemical fertilisers and pesticides: they kill the weeds faster.
The likely impact includes forest conversion to agricultural land, a drop in biological diversity as a result of monocropping and the massive use of chemical fertilizers, pesticides and herbicides, unsustainable levels of water abstraction and a greater risk of water-related conflicts with local communities and neighbouring States sharing the same transboundary river systems.
At first Kuan-Shu instructed farmers about green cultivation and the dangers of pesticides and chemical fertilizers.
Aside from organic sulfur and copper mixes, they use no chemical sprays, no artificial fertilizers or pesticides.
Although higher yields are hardly an attraction to western farmers faced with food surpluses and rock-bottom prices, the prospect of lower chemical costs through fewer applications of pesticides is more enticing.
And as the Environmental Audit Committee (at 2.15pm) prepares to give its view on whether neonicotinoid pesticides should be banned, the German chemical giant Bayer is summoned back to Parliament to explain inconsistencies in its previous evidence on how long they can linger in the environment.
DuPont is a diversified global chemical company, supplying agricultural products (such as seeds and pesticides), high-performance materials, automotive coatings, electronic materials and key industrial chemicals to industries and consumers world-wide.
Mr Hostetler, who bought his farm from an in-law who had used pesticides, had to farm the land for three years without chemical inputs before he was passed.
Incredibly, the EPA regulates such plants as pesticides and subjects them to even more stringent regulation than the deadly chemical poisons used to kill vermin, viruses or bacteria.
FORBES: 'Let's Move' Toward A More Effective Approach To Obesity
To put it bluntly, the idea was to bribe the have-nots to forgo biological and chemical arms by making available access to sophisticated means of producing pharmaceuticals, fertilizers and pesticides.
CENTERFORSECURITYPOLICY: The Non-Triumph of Hope over Experience
The researchers tested the samples for six chemical byproducts (known as metabolites) that result when the body breaks down more than 28 different pesticides.
What is more, virtually any plant used to manufacture fertilizers, pesticides or pharmaceutical products can be readily adapted to churn out large quantities of the toxic chemical agents.
Other suspicious chemical discoveries in Iraq since the beginning of the war have, after additional testing, turned out to be pesticides or other industrial chemicals.
