Abstract
Earthworms have many important roles in agroecosystems. Their feeding and burrowing activities incorporate organic residues and amendments into the soil. These activities enhance residue decomposition, formation of humus, nutrient cycling, and soil structure development. Burrows formed by earthworms also provide low resistant channels for root growth, water infiltration, and gas exchange.
