What kinds of Manure can be divided into?

1、 Commercial Manure:
1. Industrial waste: such as distiller's grains, vinegar grains, cassava residue, sugar residue, furfural residue, etc;
2. Urban sludge: such as river sludge, sewage sludge, etc. The complete classification of Manure raw material production and supply bases: silkworm excrement, mushroom dregs, kelp dregs, phosphocitric acid dregs, cassava dregs, protein mud, sugar formaldehyde dregs, amino acid Humic acid, oil dregs, Wood ash, shell powder, etc., and peanut shell powder.
2、 Biological Manure:
1. Agricultural waste: such as straw, soybean meal, cotton meal, etc.
2. Animal manure: such as chicken manure, cow, sheep, horse manure, and rabbit manure;
3. Household waste: such as food and kitchen waste;
In addition, there are mud fertilizer, smoked soil, pit soil, residue, and cake fertilizer. Soil fertilizer should be stored and dried, and the residue and cake fertilizer should be used as base fertilizer after being decomposed.
Organic fertilizer is rich in organic matter and various nutrient elements. It has the advantages of large quantity, wide sources and nutrients, but it also has the disadvantages of dirty, smelly, unsanitary, low nutrient content, slow fertilizer efficiency and inconvenient use. Inorganic fertilizers, on the contrary, have the advantages of high nutrient content, fast fertilizer efficiency, and convenient use, but they also have the disadvantage of a single nutrient. Therefore, the application of Manure usually needs to be combined with chemical fertilizer to give full play to its benefits. The combination of Organic fertilizer and chemical fertilizer can complement each other. Organic fertilizer has the original functions of improving soil, fertility, increasing yield and improving quality. These functions have been further improved after combined with chemical fertilizer. Since the use of chemical fertilizer in agricultural production, the combination of Manure and chemical fertilizer has objectively existed, but it was still in blind cooperation at that time, which was not perfect. Since the 1970s, China's fertilizer industry has developed rapidly. Through the research of many scientific workers and the practice of many farmers, fertilization methods such as soil testing and formula fertilization have been promoted and applied in production, making the combined application of organic and inorganic fertilizers more perfect.
Improving soil and enhancing soil fertility
The main substance in Organic fertilizer is organic matter, and the application of Organic fertilizer increases the content of organic matter in the soil. Organic matter can improve soil physical, chemical, and biological properties, ripen the soil, and enhance soil fertility. The proverbs of "soil depends on manure and seedlings grow on manure" in rural China, to a certain extent, reflect the role of Organic fertilizer in improving soil. The application of Organic fertilizer not only increases a lot of organic colloids, but also decomposes many organic matters into organic colloids with the help of microorganisms, which greatly increases the soil adsorption surface, and produces a lot of adhesive substances, which makes the soil particles cemented into a stable granular structure, improves the performance of soil water, fertilizer, and air permeability, as well as the ability to regulate soil temperature.
