Selection and comparison of granule and powder organic fertilizer equipment
Why use granular organic fertilizer At the beginning of the development of organic fertilizer, the product is powdery. Powder fertilizer is easy to cause segregation, difficult to control caking, poor mobility, difficult to realize mechanized fertilization, and easy to form dust in the process of application and loss. One of the ways to solve the problems caused by powder fertilizer is to realize the granulation of fertilizer. Granulation of fertilizer production line is popular. What is the nutrient leakage characteristics of granular organic fertilizer and powdery organic fertilizer in flooded soil? Some studies have shown that nitrate nitrogen, ammonia nitrogen, inorganic phosphorus, nitrate nitrogen, ammonia nitrogen and inorganic phosphorus in the soil leakage liquid after fertilizer application into flooded soil were determined With the change of potassium content, the slow-release performance of organic fertilizer was enhanced to a certain extent after granulation treatmen...
