Organic fertilizer is a kind of organic material fermented by microorganisms, such as plant residues, animal manure, organic by-products of processing industry, which can be applied to the soil to provide plant nutrition. Organic fertilizer can provide comprehensive, stable and long-term nutrient elements for plant growth, improve soil structure, improve soil buffering performance, water and fertilizer conservation capacity, promote the effectiveness of soil nutrients and reduce pesticide residues.

China has a long history and rich experience in the use of organic fertilizers, and has been in the leading position in the long history of world agricultural development. In the traditional agricultural era, organic fertilizer is often made into compost and applied nearby. The materials processed by modern organic fertilizer equipment are more extensive. With the help of the trough compost turning machine, the fermentation process can be accelerated and the fermentation cycle can be shortened. The fertilizer granulator machine equipment can make the materials into granules. For small farms, it is a very cost-effective project to make manure into organic fertilizer particles.
