What is Organic Farming?

Organic in the largest sense,  refers to agricultural production systems used to produce food and fiber.

All kinds of agricultural products are produced organically, including produce, grains, meat, dairy, eggs, fibers such as cotton, flowers, and processed food products. Organic farming management relies on developing biological diversity in the field to disrupt habitat for pest organisms, and the purposeful maintenance and replenishment of soil fertility.

Organic farmers are not allowed to use synthetic pesticides or fertilizers. Some of the essential characteristics of organic systems include: design and implementation of an "organic system plan" that describes the practices used in producing crops and livestock products; a detailed record keeping system that tracks all products from the field to point of sale; and maintenance of buffer zones to prevent inadvertent contamination from adjacent conventional fields.

Are organic yields lower?

Based on 154 growing seasons' worth of data on various crops, organic crops yielded 95% of crops grown under conventional, high-input conditions. This was by using organic farming methods developed and refined by years of grower experience, independent of the billions of dollars of support provided the agrichemical industries through USDA and the land grant system. If USDA would increase the small proportion of its research funds currently directed toward optimizing organic farming practices, organic has the potential to produce yields fully matching or surpassing those of conventional crops. Growers who go through the 3-year transition period from conventional to organic management usually experience an initial decrease in yields, until soil microbes are re-established and nutrient cycling is in place, at which point yields return to previous levels.

How do organic farmers fertilize crops? How do they control pests, diseases, and weeds?

Organic farmers build healthy soils by nourishing the living component of the soil, the microbial inhabitants that release, transform, and transfer nutrients. Soil organic matter contributes to good soil structure and water-holding capacity. Organic farmers feed soil biota and build soil structure and water-holding capacity. Organic farmers feed soil biota and build soil organic matter with cover crops, compost, and biologically based soil amendments. These produce healthy plants that are better able to resist disease and insect predation. Organic farmers' primary strategy in controlling pests and diseases is prevention through good plant nutrition and management. Organic farmers use cover crops and sophisticated crop rotations to change the field ecology, effectively disrupting habitat for weeds, insects, and disease organisms. Weeds are controlled through crop rotation, mechanical tillage, and hand-weeding, as well as through cover crops, mulches, flame weeding, and other management methods. Organic farmers rely on a diverse population of soil organisms, beneficial insects, and birds to keep pests in check. When pest populations get out of balance, growers implement a variety of strategies such as the use of insect predators, mating disruption, traps and barriers. Under the National Organic Rule, growers are required to use sanitation and cultural practices first before they can resort to applying a material to control a weed, pest or disease problem. Use of these materials in organic production is regulated, strictly monitored, and documented. As a last resort, certain botanical or other non-synthetic pesticides may be applied.
