Taking chicken manure as an example, the raw material of chicken manure has high humidity, and there are various weed seeds and bacteria in the manure. If it is used directly as fertilizer, a small amount of chicken manure may have no effect, but If there is a lot of manure, all kinds of germs will be gathered together and used directly on crops, which are prone to more weeds and various diseases and insect pests.
Drying chicken manure is mainly for harmless treatment. After the chicken manure is dried, it will reduce part of the virus and bacteria, and then ferment it. Continuous high temperatures can remove the weed seeds and bacteria and pests in it. In this way, whether it is stored or used directly, it will be safer than untreated!
So it is not so simple to make manure into fertilizer.
