How Earthworms Serve in the Soil

Earthworms tunnel through soil and spread nutrition to plants and crops.

The beneficial work that earthworms do has earned them the moniker of "nature's plow." Earthworm activity in soil benefits both small gardens and large fields of crops by administering nutrients and natural fertilization that increases vegetation and crop survival.

Movement

Earthworms are famous for tunneling through the ground, thereby providing natural aeration. This movement creates passages through which water and air can travel through the soil to nourish plants. Earthworm movement also helps to equally distribute beneficial minerals to plants and crops.

Eating the Soil

Earthworms eat leftover nutrients found in the soil, which helps the earth get rid of decomposed matter. When their bodies produce waste, the excrement serves as renewed fertilizer.

Feeding the Soil

Earthworm excrement contains several nutrients that help plants thrive. According to Cochise College, nitrogen is the most important byproduct. Materials like calcium, phosphorus and potassium are also present, according to Rutgers Cooperative Extension.
