Abstract:

Applying chemical fertilizers can increase the yield of crops, but excessive application of chemical fertilizers will cause serious pollution to the environment. The application of traditional organic fertilizer can reduce environmental pollution, but its shortcomings such as insufficient nutrition, unstable quality and slow effectiveness determine that it cannot meet the needs of crop growth. Organic fertilizer small molecule products (small molecule organic fertilizer) is a kind of fertilizer containing multiple types of small molecule organic matter, which can be directly absorbed by crop roots, improving the soil fertility, and soil microbial activity. In addition, it can also chemically bond with fertilizers to achieve the goals of improving fertilizer utilization efficiency, reducing fertilizer application, and improving agricultural quality and efficiency. To study small molecule organic fertilizers that overcome the shortcomings of fertilizers and organic fertilizers, the types of small molecule organic fertilizers were summarized, and its application effects on different crops and its impact on soil physicochemical properties and changes in soil microbial community were elaborated. The main production processes, existing problems, and future development directions of small molecule organic fertilizers were discussed.

Key words: organic fertilizers, small molecule organic fertilizer application, production process, new fertilizer, soil microbial activity
