What are the differences between BB fertilizer and compound fertilizer?
In agricultural production, BB fertilizer (blended fertilizer) and compound fertilizer are commonly used multi-nutrient fertilizers by farmers. However, they differ significantly in production processes, nutrient characteristics, and application scenarios. Choosing the right fertilizer is a key prerequisite for improving crop yield and quality. From a production process perspective, BB fertilizer production line s can be described as "simple mixing." They use large-particle urea, diammonium phosphate, and other single-element fertilizers or compound fertilizers as raw materials, completing physical mixing through mechanical stirring. There are no chemical reactions or granulation steps. The production equipment is simple, the cost is low, and the nutrient ratio can be adjusted at any time. In contrast, NPK compound fertilizer production line s involve a complex "chemical synthesis" process. The raw materials must first be crushed, and then re-granulated using an NPK...
