Basic Info of Potassium Phosphate Monobasic

What is Potassium Phosphate Monobasic?

Potassium dihydrogen phosphate is a high-efficiency instant phosphorus-potassium compound fertilizer containing phosphorus and potassium. It is used to provide nutrients needed for plant growth and development. It is suitable for any soil and crops, especially for areas where phosphorus and potassium nutrients are lacking at the same time. Crops that like phosphorus and potassium are mostly used for top dressing, seed soaking, and seed dressing outside the root, and the effect of increasing yield is remarkable. The aqueous solution can react with silver nitrate to form yellow silver dihydrogen phosphate precipitation, which can be used as an identification reaction.

Because potassium dihydrogen phosphate is more expensive and less agricultural products are produced, it is often used by soaking seeds or top dressing outside the roots. For field crops, the concentration is usually 0.2%, soaked for 18~20h, and can be sown after drying. If it is sprayed separately when used as top dressing outside the roots, the maximum concentration can be 0.5%. For example, in the jointing and booting stage of wheat and rice, it can be sprayed 1 or 2 times during the first and full blooming stages of cotton and rapeseed. When spraying twice, the interval is about 7~10 days, and the liquid consumption per mu is about 100~150kg. It can also be combined with other nutrients to form a complex nutrient solution for top dressing outside the roots.

For example, a variety of leaf fertilizers for field crops in North China are mainly composed of potassium dihydrogen phosphate, urea and some trace elements. In recent years, the composite nutrient solutions used in various parts of my country also use potassium dihydrogen phosphate as a high-concentration and relatively hydrophilic phosphorus-potassium fertilizer source. With the development of facility horticultural crops and drip irrigation and fertilizer irrigation, the demand for potassium dihydrogen phosphate products is increasing day by day.
