can. Earthworm manure is a black, uniform, natural earthy finely divided substance with good porosity, aeration, drainage and high water holding capacity. The manure contains not only various elements such as nitrogen, phosphorus and zinc, but also contains various trace elements such as iron, manganese, zinc, copper and magnesium and 18 kinds of amino acids. The organic matter content and humus content can reach about 30%. Because of its large surface area, cockroaches allow many beneficial microorganisms to survive and have the ability to absorb and retain nutrients. The cockroach dung is rich in bacteria, actinomycetes and fungi. These microorganisms not only mineralize complex substances into effective substances that plants can easily absorb, but also synthesize a series of biologically active substances such as sugar, amino acids and vitamins. The above properties of earthworms determine that it is an excellent organic fertilizer for the production of pollution-free agricultural products.
