NPK fertilizers NPK fertilizers are high in NPK elements. Compared to organic fertilizers, NPK fertilizers are faster. In modern agriculture, NPK fertilizers are absolutely essential nutrients. The NPK fertilizer industry has a bright future.
Fertilizers produced by npk fertilizer production line are made from powdered chemical materials containing nitrogen, phosphorus and potassium. Typically, urea, ammonium chloride, calcium nitrate, ammonium sulfate can be used as nitrogen sources. More importantly, phosphorus，monoammonium acid, diammonium phosphate, calcium magnesium phosphate and triple superphosphate are commonly used to provide elemental phosphates. In addition, the potassium source of NPK fertilizer includes potassium chloride, potassium salt, potassium sulfate, etc.

Npk manufacturing process consists of crusher, fertilizer mixer, granulator (double roller granulator, rotary drum granulator, etc.), screening machine, fertilizer coating machine, fertilizer automatic packaging machine, etc.
At present, the actual utilization rate of chemical fertilizers in my country is only 30%-45%, and even lower in some areas. After the application of organic fertilizers, beneficial biological activities improve soil structure and increase the soil’s ability to retain water and fertilizer, thereby reducing nutrient loss. The effective utilization rate of chemical fertilizers has been increased to more than 50%. And can reduce the amount of chemical fertilizers and fertilization costs. Therefore, the fertilization method of “mainly organic fertilizer, supplemented by chemical fertilizer” is a more reasonable fertilization method at present.
Organic fertilizers are the energy of microbial life, so chemical fertilizers are inorganic nutrients for microbial growth and development. The two combine the vitality of microorganisms to further decompose organic fertilizers. The activities of soil microorganisms can also produce vitamins, biotin, niacin, etc. Increase soil nutrients, improve soil vitality and crop growth. NPK fertilizers are used in conjunction with organic fertilizers to coordinate soil nutrients and promote crop growth.
