Organic Crop Production

Organic cropping systems mimic natural systems in a number of ways. For example, by not adding soluble fertilizers to the soil, nutrient dynamics change back to a natural state, with greater reliance on mineralization — a natural soil process — for nutrient release. In fact, crops grown under organic management have consistently shown greater association with beneficial, naturally-occurring, soil organisms such as mycorrhiza. Also, organic farmers generally use more diverse crop rotations than conventional farmers.

One criticism of organic farming is the reliance on soil tillage. Some farmers have been experimenting with no-till organic systems, thereby creating a marriage of two important innovations that bring us just a little bit closer to mimicking the natural grassland system.
