Soybean compound fertilizer and production method thereof

The present invention discloses a soybean compound fertilizer and a production method thereof, wherein the nutrients (the representation method refers to the GB18877-2009 organic-inorganic compound fertilizer national standard) comprise, by weight, 30-35% of total nutrient (N+P2O5+K2O), more than or equal to 15% of organic matters, 5-10% of compound amino acids, 0.1-0.5% of medium elements, 0.04-0.1% of trace elements, and 0.2-8% of pyrite ash. According to the present invention, the soybean compound fertilizer is prepared by carrying out pre-treatment, granulation and magnetization, such that nitrogen, phosphorus, potassium and other nutrients required by soybean growth can be provided, and the organic matters are rich; and with the magnetization treatment, the soil malnutrition caused by continuous cultivation can be improved, the physical properties of the soil can be effectively improved, nutrient absorption of crops can be promoted, the soybean root system development is good, the rootnodule development is good, the pest resistance is strong, the soybean quality is improved, and the yield per unit area is improved.
