Compared with cereal crops, soybeans are a crop that requires higher fertilizers. On fertile soil, soybean yields can be significantly increased. However, soybean must be fertilized with proper methods. Only the right amount of fertilizer, proper proportion of fertilizer and correct method can achieve maximum economic benefits. To apply fertilizer reasonably, it is necessary to clarify the characteristics and laws of soybean requirement for fertilizer. Now introduce the nitrogen requirement law of soybean:

The key period of soybean nitrogen requirement is mainly seedling stage and flowering period. During the seedling stage, after the nitrogen content in the cotyledons was exhausted, the soybean seedlings may have short-term nitrogen deficiency before the nodules have started to fix nitrogen. Applying a small amount of nitrogen fertilizer at the time of sowing can promote the growth of seedlings. At the end of flowering, the amount of nitrogen required by soybeans reached the highest peak. At the same time, the nitride in the soybean body begins to flow toward the seed, and the function of the leaf is seriously weakened due to the reduction of nitrides within the seed. The nitrogen fixation of the rhizobia begins to weaken. Applying nitrogen fertilizer at the early flowering stage is an effective measure to increase production.
