can. Vermicompost is a fine, black, homogeneous, natural earthy substance that has good porosity, air permeability, drainage, and high water retention. Earthworm feces not only contain nitrogen, phosphorus, zinc and other elements, but also contains trace elements such as iron, manganese, zinc, copper, magnesium, etc., and 18 kinds of amino acids. The content of organic matter and humus can reach 30%. Because of the large surface area of ​​the manure, many beneficial microorganisms survive, and they have the ability to absorb and retain nutrients. The maggots are 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 sugars, amino acids, and vitamins. The above properties of earthworm excrement determine that it is a good organic fertilizer that produces pollution-free agricultural products.
