Potassium dihydrogen phosphate is a highly efficient compound fertilizer.
Potassium dihydrogen phosphate is a new type of high-concentration phosphorus and potassium two-element compound fertilizer, which contains about 52% of phosphorus pentoxide and about 34% of potassium oxide. It is colorless tetragonal crystal or white crystalline powder. Easily soluble in water, the aqueous solution is acidic, and the pH value of 1 potassium dihydrogen phosphate solution is 4.6. Deliquescent. It is generally used as a buffer and culture agent in industry; as a high-efficiency phosphorus-potassium compound fertilizer in agriculture; and as a food improvement additive in food grade.
Potassium dihydrogen phosphate can be widely used in almost all types of crops such as various cash crops, grains, fruits, and vegetables. Potassium dihydrogen phosphate has many effects such as significantly increasing production and income, improving quality, resisting lodging, resisting pests and diseases, preventing premature aging, etc. It also has the effect of overcoming nutrient deficiencies caused by the aging and reduced absorptive capacity of the root system in the later stages of crop growth. Potassium dihydrogen phosphate is widely used in drip irrigation and sprinkler irrigation systems due to its good solubility.
How to use potassium dihydrogen phosphate
Fruit trees should be sprayed on the leaves every 10-15 days before flowering, after flowering, during the young fruit stage, and during the fruit expansion stage. Potassium dihydrogen phosphate 500-800 times. For vegetables, during the seedling stage, before flowering, after flowering, and during the fruiting period, spray 300-500 times of potassium dihydrogen phosphate on the leaves every 10 days or so. For cash crops such as cotton, 300-500 times of potassium dihydrogen phosphate should be sprayed on the leaves every 7 days or so during the seedling, budding, flowering and boll-bearing stages.
Avoid high temperatures. When using high-concentration potassium dihydrogen phosphate, be sure to avoid high-temperature periods. Generally, high-concentration potassium dihydrogen phosphate cannot be used in high-temperature seasons. It can be used before 10 a.m. or 4 p.m. After spraying. Avoid alkaline fertilizers. Potassium dihydrogen phosphate can be mixed with most acidic and neutral fertilizers and pesticides, but it cannot be mixed with alkaline fertilizers and pesticides.
