Due to the deterioration of soil physical and chemical properties, the decline of soil fertility and the pollution of ecological environment caused by the application of chemical fertilizer, and the current international energy shortage, the high price of chemical fertilizer, resulting in the continuous decline of agricultural production efficiency, the development of organic fertilizer has become an urgent task. Fertilizer production machine has become an important part of agricultural development.
Why is granular organic fertilizer better
Powder fertilizer is easy to form dust and lose in the process of application. One of the solutions is to realize the granulation of fertilizer. 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 treatment; there were some differences in nutrient dissolution and leakage between granular fertilizer and powdery fertilizer, and the leakage loss of nitrate nitrogen and inorganic phosphorus could be significantly reduced by applying granular fertilizer.
How to choose organic fertilizer equipment
Although the effect of granular organic fertilizer is better. But for investors, whether to choose powder organic fertilizer equipment or granular fertilizer production machine, they should make a final decision according to their own specific situation.
When investing in fertilizer production projects, the first thing to consider is the financial strength of individuals. Granular organic fertilizer production line needs more investment and equipment, and different process fertilizer granulators are different, such as disc granulator machine, flat die extrusion pellet mill, drum granulator, organic fertilizer granulator, roller granulator, etc. If you are also engaged in the cultivation of grain or cash crops, if you do not consider the market, the powder with low investment cost can be considered. If it is put into the market, the granular organic fertilizer favored by users is more suitable.
