What kind of fertilizer does organic fertilizer refer to?

Organic fertilizer refers to a natural fertilizer that converts biomass into fertilizer through biological fermentation, decomposition, or composting, without the use of artificial chemicals such as synthetic fertilizers, pesticides, and growth regulators. Its main components are animal and plant residues, kitchen waste, rural waste, etc., which are formed by the decomposition and transformation of biological organic substances. The use of organic fertilizers can improve soil quality, increase soil fertility, promote soil microbial activity, and improve soil structure. At the same time, the use of organic fertilizers can reduce the use of fertilizers and pesticides, reduce environmental pollution, protect the ecological environment, and improve the quality and safety of agricultural products. Organic fertilizer is a safe, environmentally friendly, and ecological choice widely used in organic agricultural production and modern agriculture.
