Compared with ordinary organic fertilizer, the biotechnology content of organic fertilizer production is relatively high, in addition to adding to promote the decomposition of organic materials, in the decomposition process, there is the decomposition of biological agents to achieve directional decomposition and deodorization. After treatment, microorganisms with specific functions in the production process are added, and the rotary drum granulator granulates the raw materials to improve the effect of the product. At the same time, compared with the common organic fertilizer, the production cost of bio organic fertilizer is higher, mainly used in vegetables, fruits, medicinal materials, tea, tobacco, high value-added crops, and achieved good results.
