Compound Fertilizer

Compound fertilizers refer to chemical fertilizers containing two or more nutrient elements in nitrogen, phosphorus and potassium. Compound fertilizers have the advantages of high nutrient content, few side components and good physical properties. For balanced fertilization, it can improve fertilizer utilization and promote high crop yields. Stable production plays a very important role.
In the production of compound fertilizers, soil testing formulas are often used to measure soil nutrients. Soil testing and formula fertilization are based on soil testing and fertilizer field experiments. On this basis, the application quantity, fertilization period and application method of nitrogen, phosphorus, potassium and medium and trace elements are put forward.
Common granulation processes for compound fertilizers are: drum granulation, disc granulation, shotcrete granulation, tower granulation, etc.
Chemically synthesized Compound Fertilizer refers to compound fertilizers synthesized through obvious chemical reactions, which are made through chemical (chemical) action or ammoniated granulation process. Common types mainly include diammonium phosphate, monoammonium phosphate, nitrophosphate fertilizer, nitric acid Potassium and potassium dihydrogen phosphate, etc. This type of compound fertilizer contains two or more elements required by crops, and has high nutrient content, which can supply the nutrients required by crops in a balanced and long-term manner, and improve the effect of fertilization and yield increase.
The total amount of nutrients of compound fertilizers is generally relatively high, and there are many types of nutrients. One application of compound fertilizers can supply at least two or more main nutrients of crops at the same time.
