In many places, the soil lacks potassium and medium and trace elements in different degrees. Due to the imbalance of long-term fertilization, the organic matter, potassium, and trace elements are insufficient, the PH of the soil decreases, the corrosion of the knots and non-point sources is serious, and the crop pests and diseases are serious, and the pesticides are serious. The application rate is large, which affects the quality of agricultural products. To complete the repair and maintenance of the soil, the demand for potash is an inevitable choice. At present, the use of potassium formate in potash is also innovative and diversified.

Potassium is the "grain" of grain. Potassium fertilizers currently used in the market are generally potassium dihydrogen phosphate, potassium sulfate, potassium nitrate, potassium chloride and their compound fertilizers. Potassium chloride is not considered because it contains very high harmful substances, chloride ion.

Potassium formate as foliar fertilizer is widely used in cotton, tobacco, flax, rice, wheat, maize, sugarcane and other crops, oranges, grapes and other fruits and vegetables. Potassium requirement of different crops and potassium uptake capacity of roots are different, and the response degree of crops to potassium fertilizer is also different. From the results of years of potassium fertilizer application, potassium fertilizer is used in maize, cotton, sweet potato and oil crops. Yield increase was the best, followed by other crops such as wheat.

Potassium formate has a very high solubility (ten or even tens of times as much as other potassium fertilizers) and a very low content of chloride ions (one thousandth of other potassium fertilizers). It is a good choice for producing high-potassium and high-concentration drip irrigation liquid fertilizer. It belongs to high-potassium type potassium fertilizer. It can absorb completely without residue and increase the absorption efficiency of other fertilizers (mainly nitrogen fertilizers).

When potassium formate foliar fertilizer is dissolved from solid to liquid and diluted by liquid, use deionized water or distilled water as far as possible.
