Bean cake can be directly used as base fertilizer, but it cannot replace organic fertilizer. More attention should be paid to stay away from the roots, and the amount of application should not be too large. Generally, it is appropriate to control the dosage of 5-1 kg per mu, otherwise it is easy to burn seedlings. Excessive application will lead to a large number of organic acids in the transformation process of soybean cake, which will directly affect the ecological balance of soil.

bean cake is mainly a by-product of oil extraction from soybeans or black beans. It has certain nutritional value when applied as fertilizer, but it takes a long transformation period, generally it takes 18-22 days to meet the requirements of crop absorption. When it is used, bean cake should be fully fermented with biological bacteria liquid before fertilization, which is more conducive to the absorption, utilization and growth of plants.
