In recent years, a large amount of chemical fertilizer has made the physical and chemical properties of the soil worse, and it has affected the quality of crops and the sustainability of yield. The fertilizer products produced by fertilizer equipment have increased soil organic matter, nitrogen, phosphorus, potassium and various trace elements. The content of the soil, reducing the bulk density of the soil and increasing the total porosity, and maintaining the continuous increase of crop yield are effective methods to solve the above problems.
