Earthworms create tunnels in the soil by burrowing, through which oxygen and water can enter and carbon dioxide can leave the soil. Earthworms eat the organic matter such as decaying vegetation or leaves or cattle dung. Plants cannot use this organic matter directly. After organic matter is digested, the earthworm releases waste from their bodies called castings. Castings are very important to the fertility of the soil. The castings contain high amounts of nitrogen, potassium, phosphorus, calcium, and magnesium. Castings contain 5 times the available nitrogen, 7 times the available potash, and 1½ times more calcium than found in good topsoil that the plant can use. We make available qualitative earthworms for Vermi-Composting at farmer’s field.
