Gmos burst onto the scene in 1996 with the rapid commercial introduction in the united states of genetically-engineered corn (maize), cotton, and soybeans, although genetically-engineered horticultural crops, such as tomatoes, had been approved as early as 1992. Genetically modified crops (also called biotech crops) have been intentionally altered through genetic engineering-the elimination, alteration, or introduction of new genetic elements, including from one unrelated species to another. Genetically modified crops (gmcs, gm crops, or biotech crops) are plants used in agriculture, the dna of which has been modified using genetic engineering methods in most cases, the aim is to introduce a new trait to the plant which does not occur naturally in the species.

Title the impact of genetically engineered crops on farm sustainability in the united states / summary since genetically engineered (ge) crops were introduced in 1996, their use in the united states has grown rapidly, accounting for 80-90 percent of soybean, corn, and cotton acreage in 2009.
The usda also helps industry respond to consumer demands in the united states and overseas by supporting the marketing of a wide range of agricultural products produced through conventional, organic, and genetically engineered means. Th is report explores the impact of the adoption of genetically engineered (ge) corn, soybean, and cotton on pesticide use in the united states, drawing principally on data from the united states department of agriculture. In summary, one of the greatest promises of the agri-bio industry — that gmo crops would reduce the use of chemicals — is sadly untrue: pesticide use has increased by 404 million pounds from the time genetically engineered crops were introduced back in 1996, to the year 2011.
Sustainable agriculture practices can protect the environment and produce high-quality, safe, and affordable food our goal is to promote such practices while eliminating harmful “factory farming” methods and strengthening government oversight of genetically engineered food.

Genetically engineered (ge) crops cover approximately half of us cropland although delivering environmental and economic gains for adopting farmers, the long-term potential of the crops to foster sustainable agriculture remains controversial. 52 genetically modified crops may have indirect environmental effects as a result of changing agricultural or environmental practices however, it remains controversial whether the net effect of these changes will be positive or negative for the environment.
