Organic farmers rotate many crops through the same field, providing a variety of root structures and organic matter to structure and feed the soil.
Cover cropping works in the same way, adding variety to a crop rotation and nutrients to soil.
Organic farmers encourage the presence of natural predators like birds and bats that consume pests, supporting natural ecosystems.
Practices like composting encourage diversity of microorganisms in the soil.
Reduced tillage and organic no-till encourage life in the soil.
Integrating livestock into crop production further adds variety above and below ground.
