Soil fertility and management


Soil is one of the most important resources. Organic farmers aim to maintain the long-term fertility of the soil. Biologically active soil will decompose organic matter faster, so bacteria, fungi and earthworms are encouraged. When soil organisms decompose organic matter, nutrients essential for plant growth are recycled back into the soil to 'feed' the next crop. Farmers must also protect soil structure. For air, water and nutrients to reach and be absorbed by plant roots, they need pores in the soil.
