Nitrogen, phosphorus and potassium are nutrient elements for plant growth. Potassium formate is a relatively new type of water-soluble fertilizer, which can be solid or liquid. Its main function is to provide and supplement nutrients for crops according to plant nutritional characteristics and nutritional status, and improve crop growth.

Potassium formate water-soluble fertilizer has these effects:

1. First of all, water-soluble foliar fertilizer requires very high solubility. Potassium formate is used as water-soluble and high-potassium water-soluble fertilizer. The solubility is very high. 337g is dissolved at 20 degree centigrade in 100g water and 313g is dissolved at 10 degree centigrade in 100g water. The saturated solution PH of potassium formate water-soluble fertilizer is about 9, which can improve soil acidification to a certain extent.

2. Many crops need adequate nitrogen fertilizer to ensure and promote nutritional growth in early growth stage. In the seedling stage, topdressing nitrogen fertilizer; in the middle stage, attention should be paid to the suitable application of phosphorus fertilizer; in the large stage, topdressing potassium fertilizer is the main method, and potassium formate water-soluble fertilizer can promote the absorption of nitrogen by crops.

3. Potassium formate water-soluble fertilizer can also promote fruit setting and improve fruit quality.

The direct function of potassium formate foliar fertilizer is to increase plant growth and crop yield. Although the cost of planting will increase slightly, in fact, the amount of potassium formate in organic fertilizer is small, effective and can supplement the nutrition needed by crops in time. It is widely used in cotton, tobacco, flax, rice, wheat, corn, sugarcane and other crops as well as fruits and vegetables such as oranges, grapes.
