The production of compound fertilizers often uses soil testing formulas to measure the nutrient status of the soil. Soil testing formula fertilization is based on soil testing and fertilizer field experiments, and proposes the application quantity, fertilization period, and application method of nit

The common granulation processes for compound fertilizers include drum granulation, disc granulation, spray granulation, and tower granulation.High concentration nitro compound fertilizer is produced by the high tower melt rotation granulation method. This technology sprays molten nitrate, phosphoru

The two national standards GB18382-2001 "Labeling, Content and Requirements for Fertilizer" and GB/T15063-2009 "Compound Fertilizer" issued by the General Administration of Quality Supervision, Inspection and Quarantine of China have officially come into effect in the production and distribution sta

Rice specificIt is mainly made from urea, ammonium phosphate, and potassium chloride, with an effective nutrient content of ≥ 25% for nitrogen, phosphorus, and potassium. It can be used as base fertilizer and topdressing, with a general usage of 60-75 kilograms per mu. Base fertilizer accounts for 6

According to fertilizer scienceA considerable portion of compound fertilizers sold in the market do not meet the national DB15063-94 standard. According to national standards, the effective nutrient content of compound fertilizer (compound fertilizer) should be ≥ 40% for high concentration nitrogen,

Nutrient elementsThe total amount of nutrients in compound fertilizer is generally high, with a variety of nutrient elements. A single application of compound fertilizer can provide at least two or more main nutrients for crops at the same time.Uniform structureFor example, ammonium phosphate does n
