    Corn growing in a field

USDA has long been at the forefront of organic farming. To obtain USDA organic certification, a field must go through a 3-year transition during which only organic amendments are added.


Here at ARS, our scientists help organic farmers overcome the challenges they face related to productivity, environmental stewardship, and energy efficiency. We research the biological and physical processes innate to plants, soils, invertebrates, and microbes that naturally regulate pest problems and soil fertility, providing farmers with natural alternatives to using synthetic pesticides and fertilizers to keep their crops healthy and plentiful.
