Organic farming is agriculture that makes healthy food, healthy soils, healthy plants, and healthy environments a priority, along with crop productivity. Organic farmers use biological fertilizer inputs and management practices such as cover cropping and crop rotation to improve soil quality and build organic soil matter. By increasing the amount of organic matter in the soil, organic farmers enhance the soil’s ability to absorb water, reducing the impacts of drought and flooding. Improving soil organic matter also helps it to absorb and store carbon and other nutrients need to grow healthy crops, which, in turn, are better able to resist insects and diseases.

Organic production systems do not use genetically modified (GM) seed, 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 recordkeeping system that tracks all products from the field to point of sale; and maintenance of buffer zones to prevent inadvertent contamination by synthetic farm chemicals from adjacent conventional fields.

Organic farms use production practices with environmental benefits such as water management practices, no-till or minimum tillage, habitat maintenance for beneficial insects and vertebrates, and biological pest control. These ecologically protective practices contribute to enhanced ecosystem services and benefit water quality, soil health, and biodiversity.

Conventional farming typically uses minimal crop rotations, growing the same single crop year after year on the same land. This practice, known as mono cropping causes the depletion of nutrients and minerals. In order to continue growing crops in this depleted soil, nutrients and minerals must be added back in the form of hydrocarbon based fertilizers and mined minerals such as phosphate. Conventional GM farming is dependent on earth-based non-renewable resources. Monocultures and the resulting poor health open the way for infestations of insects, diseases and weeds. Healthy bio-diverse soil keeps these infestations in check. The lack of biodiversity requires synthetic pesticides and herbicides to be used, further destroying the national soil biology.

Healthy soils form the foundation of organic production. Healthy soils have good structure (tilth), which allows them to absorb and hold moisture, drain well, maintain adequate aeration, and foster deep, healthy crop root systems. Such soils sustain crops through dry spells, require less irrigation water, and undergo less ponding, runoff, and erosion during heavy rains.

The Natural Resources Conservation Service (NRCS) has identified four guiding principles that support healthy soils: 1) minimize disturbance, 2) maximize biodiversity, 3) keep soil covered, and 4) maintain living roots. These principles provide the foundation for a resilient farm system.

The USDA National Organic Standards require certified producers to implement crop rotation, cover cropping, tillage, nutrient management, and other practices that improve and maintain the physical, chemical, and biological condition of the soil.
