According to the USDA’s National Agricultural Statistics Service (NASS), biotechnology plantings as a percentage of total crop plantings in the United States in 2012 were about 88 percent for corn, 94 percent for cotton, and 93 percent for soybeans. NASS conducts an agricultural survey in all states in June of each year. The report issued from the survey contains a section specific to the major biotechnology derived field crops and provides additional detail on biotechnology plantings. The USDA does not maintain data on international usage of genetically engineered crops. The independent International Service for the Acquisition of Agri-biotech Applications (ISAAA), a not-for-profit organization, estimates that the global area of biotech crops for 2012 was 170.3 million hectares, grown by 17.3 million farmers in 28 countries, with an average annual growth in area cultivated of around 6 percent. More than 90 percent of farmers growing biotech crops are resource-poor farmers in developing countries. ISAAA reports various statistics on the global adoption and plantings of biotechnology derived crops.
