Organic fertilizer is mainly derived from plants and animals, it is a carbon containing material which is applied to the soil to provide plant nutrition as its main function. Through the processing of biological substances, animal and plant wastes and plant residues, the toxic and harmful substances are eliminated and beneficial substances are increased, including a variety of organic acids, peptides, and rich nutrient elements nitrogen, phosphorus and potassium. It can not only provide comprehensive nutrition for crops, but also can increase and update soil organic matter, promote microbial reproduction, improve the physical and chemical properties and biological activity of soil, which is the main nutrient of green food production.
