2. Features: Both types of fertilizers are rich in organic matter such as protein, fatty acids, organic acids, etc., and contain various nutrients. However, many of its elements cannot be directly used by plants and need to be decomposed by microorganisms. So the fertilizer effect is lasting. Most of potassium is soluble in water and has high effectiveness, while the urea component is converted quickly and can be used directly. Among the two types of fertilizers, poultry feces and human feces decompose quickly and have a fast fertilizer effect.
3. Application method: manure and urine should be used as top dressing after short-term storage. The decomposed animal manure and barn manure should be used as base fertilizer, and it can also be used as top dressing and seed fertilizer. When used as base fertilizer, it can be used for full spreading or concentrated application (applied around the planting hole ). This is a particularly simple fertilizer production process.
(3) Composting and composting
1. Refers to the use of domestic garbage, waste, animal and plant residues, human and animal manure and other raw materials, through mixed composting or retting and fermentation.
2. Features: Rich in organic matter, containing various nutrients, the PH value is neutral or slightly acidic. Among them, composting is more efficient than retting.
3. Application method: It is suitable to be used as a base fertilizer, and it is generally required to be fully decomposed and mixed together when pour into the ground or prepare the cultivation soil. Recommend a professional compost windrow turner.
