Superphosphate is a cheap chemical fertilizer commonly used in agricultural production. Its main components are calcium phosphate and calcium dihydrogen phosphate. Calcium phosphate is hardly soluble in water and it is difficult to exert its effect. It is calcium dihydrogen phosphate that does not have a large content in superphosphate. However, one of the biggest drawbacks of calcium dihydrogen phosphate is that it easily combines with some inorganic elements in the soil to form insoluble substances and loses its effectiveness. The organic fertilizer can effectively overcome this shortcoming, and it can also make the insoluble calcium phosphate gradually convert into soluble. Therefore, mixing calcium superphosphate with organic fertilizer can greatly improve fertilizer efficiency. The specific approach is: smash the superphosphate, sifting the powder at a ratio of about 1:4 with pig manure, chicken manure, beef and sheep manure, manure fertilizer, straw powder, etc., and after full fermentation, take the agglomerate application. Into the previously dug wells as base fertilizer, then fill the crops. The amount of application depends on the need. This method has the following advantages: 1. It can reduce the contact between superphosphate and soil, effectively avoiding soluble phosphorus from becoming insoluble and reducing fertilizer efficiency. 2, superphosphate and organic fertilizer block mixed into the soil after the formation of loose mass, easy to infiltrate the water to dissolve soluble phosphorus, plant roots are also easy to reach the inside of the mass to absorb water-soluble phosphorus. Moreover, the root acid and organic fertilizer secreted by the root tip of the plant slowly act on the insoluble calcium phosphate and gradually dissolve the calcium phosphate, thereby further increasing the utilization of phosphorus in the calcium superphosphate. 3, superphosphate and organic fertilizer mix, but also a single fertilizer for the compound fertilizer, increased the types of elements applied to plants, but also promote the absorption and utilization of phosphorus plants, to better meet the nutritional needs of the crop. 4. When superphosphate and organic fertilizers are mixed into the soil, it can overcome the disadvantages of conventional methods such as excessively increasing the concentration of phosphorus in the soil and affecting the normal life and activities of microorganisms in the soil and inhibiting the absorption of nutrients by plants. The activity of the soil also increases the absorption efficiency of the nutrient elements by plants. In addition, production practices have proved that the current fertilization of iron, zinc, manganese and other trace elements fertilizers and organic fertilizers will greatly increase their fertilizer efficiency.
