No mixed use of zinc fertilizer and phosphate fertilizer
When zinc sulfate and phosphate are mixed and applied together, zinc phosphate is formed, which is not easily soluble in water. The roots of crops are difficult to absorb and utilize this zinc. Therefore, when zinc sulfate is applied, it must avoid contact with phosphorus fertilizers such as calcium superphosphate, heavy superphosphate, diammonium phosphate and potassium dihydrogen phosphate, and it must not be mixed together. With zinc sulfate as base fertilizer, zinc sulfate and farm manure can be evenly mixed and applied together, and phosphorus fertilizer can be applied when sowing. Phosphorus fertilizer can also be evenly mixed in farm manure as base fertilizer, and zinc sulfate can be applied when sowing. This creates a barrier between zinc and phosphate fertilizer, preventing them from touching each other.

Rape is a crop that needs more boron. Lack of boron at the seedling stage, the root system stops growing, there is no root hair or no lateral root, the growth point changes from brown to scorched and dies; timely application of boron fertilizer plays an important role in high yield and good quality of rape. The specific method is: boron fertilizer as base fertilizer is directly applied to the soil, which can be used in rape.

How to apply phosphorus Fertilizer to Wheat
Wheat is a crop that needs more phosphorus. Scientific application of phosphate fertilizer is one of the key measures to improve the efficiency of phosphate fertilizer, reduce the cost of fertilization and promote high quality and high yield of wheat. 1. After composting and fermentation with organic fertilizer, the application of organic fertilizer is rich in organic matter, phosphoric acid and a variety of organic weak acids, which can turn insoluble phosphorus into soluble phosphorus.
