Effect of Rational Application of Organic Fertilizer on Soil Properties: A Review |
| |
| Abstract: | To understand the effect of organic fertilizer on improving soil fertility and regulating soil, we reviewed the research progress of organic fertilizers on N, P and K nutrients, soil bulk density and porosity, soil microorganisms, and soil heavy metals in recent years. The main research content included that rational application of organic fertilizers could increase the content of mineralized nitrogen in soil and promote different forms of nitrogen transformation; the content of both available phosphorus and organic phosphorus in soil could be increased, and the contents of available potassium and slowly available potassium could be increased significantly. Organic fertilizers could reduce surface soil bulk density and effectively maintain soil porosity, promote soil microbial activity and increase its biomass. The selective application of organic fertilizer could fix and purify the heavy metals in soil, however, the improper application could lead to heavy metal pollution, etc. Besides, we discussed the research trends of organic fertilizers in soil pollution and remediation, aiming to maximize the efficiency of organic fertilizers application in soil and increase the utilization ratio of soil
fertilizers. |
