There are many kinds of organic fertilizer, among which bio-organic fertilizer is the leader. Biofertilizer refers to a kind of fertilizer with both microbial fertilizer and organic fertilizer effects, which is composed of specific functional microorganisms and organic materials, mainly from animal and plant residues (such as animal manure, crop straw, etc.) and treated by harmless treatment and decomposed organic materials. It is different from organic fertilizer produced only by natural fermentation (decomposition). Bio-organic fertilizer products contain not only higher organic matter, but also microorganisms with specific functions, which is the essential characteristics of such products. Moreover, the microorganisms contained in the soil show certain fertilizer effects, such as enhancing soil fertility, manufacturing and assisting crops to absorb nutrients, activating insoluble compounds in the soil for crop absorption and utilization, or producing a variety of active substances and disease-resistant substances, which can stimulate and regulate the growth of crops. It can decrease or reduce the occurrence of crop diseases and insect pests, and improve the quality of agricultural products.
Compared with ordinary organic fertilizer, the technology content of biofertilizer production is relatively high. In order to achieve directional decomposition and deodorization, biological agents should be added to the decomposition process of organic materials. In addition, microorganisms with specific functions should be added to the products to enhance the effect of the products.
In the production process, there is also a difference between biofertilizer and common organic fertilizer. In the fertilizer production equipment, the biofertilizer production equipment is the same as the ordinary organic fertilizer production equipment, including fertilizer granulator machine, mixer, crusher, drum screening machine and other equipment. The difference between the two is how to protect the functional bacteria in the production process and improve the survival rate of the strains in order to maximize the fertilizer efficiency.
