The invention discloses a soybean dedicated biological organic green fertilizer which is characterized by being prepared from the following raw materials in parts by weight: 100-120 parts of human and animal excreta, 50-60 parts of corn straw, 35-50 parts of rapeseed cake meal, 25-30 parts of urea, 21-25 parts of ammonium hydrogen carbonate, 35-40 parts of diammonium phosphate, 10-13 parts of a limestone powder, 1-2 parts of zinc oxide, 29-35 parts of animal urine, 17-23 parts of potassium chloride, 24-28 parts of peanut cake meal, 5-7 parts of brown sugar, 5-7 parts of an EM agent, 8-10 parts of a soil improvement agent, and a proper amount of water. The organic fertilizers are fermented and then are mixed with the general chemical fertilizers, and the melting urea is utilized to coating the surface, so that a slow release effect is played, subsequent nutrients for soybean are allowed to be sufficient, the utilization rate of the fertilizer is improved, the fertilization cost is substantially reduced, the yield of the soybean is improved, and economic benefits are also correspondingly improved; and the soybean dedicated biological organic green fertilizer is green and environmentally friendly, and is convenient to popularize and apply.
