What is the solubility of potassium dihydrogen phosphate?

Potassium dihydrogen phosphate is a good fertilizer, suitable for melons and fruits, vegetables, grain and oil and other economic crops, can effectively increase production and income, improve crop fruit quality, lodging resistance, resistance to diseases and insect pests, strong seeds, etc., what is the solubility of potassium dihydrogen phosphate?

What is the solubility of potassium dihydrogen phosphate?

At 0 ℃ at room temperature, the solubility of potassium dihydrogen phosphate was 14.8 g at 10 ℃, 18.3 g at 20 ℃, 22.6 g at 30 ℃, 28 g at 40 ℃, 33.5 g at 50 ℃, 40.7 g at 50 ℃, and then increased by 10 g for every 10 ℃, and 83.5 g at 100 ℃. Therefore, it is recommended that the room temperature should be about 18 degrees.

Second, how to use potassium dihydrogen phosphate?

1. Spraying method: focus on spraying the back of leaves, and strive for the best absorption effect. Generally, foliar spraying is the main method. It was sprayed once every 10 days, for 2 times in a row. If you spray fruit trees, spray every 10-15 days before flowering, after flowering, young fruit stage and fruit expansion period.

2. Spraying time and concentration: spraying in the critical period or peak period of phosphorus and potassium uptake by crops has the best effect. For example: extra-root fertilization, the general concentration of 0.05%-0.1% in seedling stage, 0.2%-0.3% in the middle and later stage, foliar spraying; in the growing period, 0.2%-0.3% potassium dihydrogen phosphate solution is commonly used to spray leaves, which can make its branches strong and leafy; spraying 0.3% potassium dihydrogen phosphate solution 2 times in the bud stage can make the flowers larger and more and brightly colored.

3, mixing situation: potassium dihydrogen phosphate can be mixed with most acidic pesticides and fertilizers, 0.5% to 1% of potassium dihydrogen phosphate solution pH is between 4.6 and 6, generally will not cause precipitation with other substances.

However, when mixing, the concentration should not be too high or too small, depending on the specific local conditions, it is recommended that you use it under 300 times the liquid to avoid leaf zoom.
