Nitrogen, phosphorus, potassium large chemical fertilizer and high content compound fertilizer are all products produced by regular manufacturers and up to the standard. Other compound fertilizers or compound fertilizers have the phenomenon of fake and inferior quality in varying degrees. Five identification methods should be mastered: first, whether the production license number and registration certificate number are complete, the products with incomplete certificate number are generally produced by individual small factories or underground black factories, and the quality is extremely unreliable; second, the specific gravity and smoothness of particles are more important and too smooth, the adulterated components are large; third, the production date, the longer the storage time, the total nutrients of fertilizer will gradually decrease. Four smell fertilizer, the general urea compound fertilizer smell is less, the nutrient content is relatively stable, ammonium nitrate or ammonium chloride compound fertilizer, the smell is relatively large, the nutrient content is not stable, the use effect is poor.

Second, it is necessary to master the types and characteristics of chemical fertilizer.

At present, chemical fertilizers are no longer urea, diammonium and potash fertilizers. In recent years, many compound fertilizers and special fertilizers have been added. It is necessary to understand the content and function of nitrogen, phosphorus, potassium and trace elements in various fertilizers, and choose and buy chemical fertilizers according to their own actual needs.

Third, chemical fertilizers should be selected and purchased according to soil fertility.

It is necessary to carry out soil testing and formula fertilization, grasp the soil types, nitrogen, phosphorus and potassium content, and organic matter content of their own land, adjust measures to local conditions, make up for what they lack, how much they lack, and use chemical fertilizers scientifically and rationally.

Fourth, it is necessary to buy fertilizer according to the law of fertilizer demand for different crops.

The type and quantity of fertilizers needed in the growth and development of corn, soybean, rice, vegetables, melons and fruits are different and can not be the same. In recent years, scientific research and extension personnel have developed a variety of special fertilizers with good results. Such as corn special fertilizer, rice special fertilizer, etc., can be purchased according to the needs.
