What are the differences between BB fertilizer and NPK compound fertilizer?
In agricultural production, BB fertilizer (blended fertilizer) and NPK compound fertilizer are commonly used compound fertilizers. Although both contain the core nutrients of nitrogen, phosphorus, and potassium, they differ fundamentally in production logic, nutrient characteristics, and applicable scenarios. Choosing the right fertilizer is key to achieving precise fertilization and improving yield and quality. The production process is the most significant difference between the two. NPK compound fertilizer production uses a "chemical synthesis followed by granulation" model, where nitrogen, phosphorus, and potassium raw materials are fused into a single compound through chemical synthesis reactions, and then processed into uniform granules through granulation and drying. BB fertilizer production , on the other hand, uses a "granulation followed by blending" method. High-concentration nitrogen, phosphorus, and potassium single-nutrient fertilizers or single-nutri...
