Fermented bean cake residue can not be used as feed as fertilizer. If the residue after fertilization is used as feed, the nutrition is insufficient.

Bean cake, cake-shaped bean dregs extracted from soybean oil, belongs to organic fertilizer, and its main components are ammonium nitrate, phosphate fertilizer and potassium phosphate. Don't underestimate it, its price is equivalent to that of soybeans before oil pressing and more than twice that of corn. Bean cake contains a lot of energy substances. After returning to the field, the soil biological activity increased sharply, and the contact enzyme activity increased by 47%. It can reduce soil capacity, loosen soil, improve air permeability, reduce specific resistance to tillage and obviously improve soil structure. In addition, it is also of direct help to the taste of rice.

Almost all organic fertilizers, such as bean cakes and feces, need to be fully fermented and decomposed before they can be applied. It should be that we have tried to expand fermentation by indigenous methods one after another, and the purchased bean cakes must also be tested for non-GMO.
