As an NPK Bulk Blended Fertilizer Manufacturer, share with you.
Generally, the compound fertilizers we see on the market have the difference between ternary compound fertilizer and two-component compound fertilizer. NPK is a ternary compound fertilizer, and NP is a two-component compound fertilizer. So what does it mean? Nitrogen, Phosphorus and Potassium Compound Fertilizer is abbreviated as NPK, which is a compound fertilizer made by chemical methods containing all three nutrients of nitrogen (N), phosphorus (P) and potassium (K), also called ternary compound fertilizer. And NP refers to binary compound fertilizer, that is, compound fertilizer containing nitrogen (N) and phosphorus (P). Of course, any two compound fertilizers containing nitrogen, phosphorus and potassium at the same time can be called binary compound fertilizer.

In the production of compound fertilizers, soil testing formulas are often used to measure the nutrient conditions of the soil. The soil testing formula fertilization is based on soil testing and fertilizer field trials. According to the law of crop fertilizer requirements, soil fertilization performance and fertilizer effects, it is reasonable to apply organic fertilizers. On the basis of this, the application quantity, application period and application method of fertilizers such as nitrogen, phosphorus, potassium and middle and trace elements are proposed. In layman's terms, it is the scientific application of formula fertilizers under the guidance of agricultural science and technology personnel. The core of the soil testing and formula fertilization technology is to adjust and solve the contradiction between the fertilizer requirement of the crop and the fertilizer supply of the soil. At the same time, the nutrient elements required by crops are supplemented in a targeted manner. What elements are missing in crops can be supplemented as much as needed to achieve a balanced supply of various nutrients to meet the needs of crops; to improve fertilizer utilization and reduce dosage, and increase crops The purpose of output, improving the quality of agricultural products, saving labor, saving expenditure and increasing income.
The common granulation processes of compound fertilizers are: drum granulation, disc granulation, spray granulation, high tower granulation and so on.
