Field crops are mainly applied to nitrogen fertilizer, and economic crops such as vegetables, tobacco, grapes, cotton, etc., in addition to nitrogen fertilizers, should be applied to potash fertilizer. For example, spring corn crops are treated with urea one-time base fertilizer as a reference.

The other half of the urea was topdressed and applied at the end of July and early August. The latter's nitrogen fertilizer utilization rate can be increased by 10% to 20%. This indicates that the utilization rate of nitrogen fertilizer application is significantly higher than that of all nitrogen fertilizers. Regarding the method of applying nitrogen and potassium fertilizer in summer, it is necessary to ditch the soil to avoid the loss of nitrogen volatilization caused by nitrogen application and the potassium fixation caused by the alternating dry and wet of potassium fertilizer on the surface.
