Compound fertilizer has the advantages of high nutrient content, less accessory components, and good physical properties. It plays an important role in balancing fertilization, improving fertilizer utilization, and promoting high and stable yields of crops. However, it also has some shortcomings. For example, its nutrient ratio is always fixed, and the types of nutrients, quantities, and proportions required for different soils and crops are diverse. Therefore, it is recommended to use soil testing before use to understand the texture and nutritional status of field soils. It is also necessary to pay attention to the application of unit fertilizers in order to obtain better results.

The foliar fertilizer granulator is a soft material that is uniformly mixed, and under the pressure of a guillotine knife, the material is forced to pass through a screen and is cut by a doctor blade to obtain column-shaped particles with uniform length.
