Potassium Phosphate Monobasic

Molecular formula: H2KO4P

Molecular weight: 136.085541

CAS number: 7778-77-0

Physical and Chemical Properties: 
This is a high-concentration phosphorus and potassium compound fertilizer, appearing as colorless to white crystals or crystalline powder, and is odorless. It contains 52% P2O5 and 34% K2O. It has low hygroscopicity, good physical properties, and is readily soluble in water, dissolving 23g per 100ml of water at 20°C. The aqueous solution is acidic.

Uses: 
1. Promotes nitrogen and phosphorus absorption. Potassium dihydrogen phosphate promotes nitrogen and phosphorus absorption by crops, rapidly replenishing phosphorus, increasing crop yield and thousand-grain weight, and plays a special role during specific physiological periods of crops.
2. Promotes photosynthesis. Potassium enhances crop photosynthesis during growth, accelerating nutrient production and conversion.
3. Improves crop resistance to stress. Potassium dihydrogen phosphate can improve crop resistance to stresses, such as drought, resistance to dry hot winds, waterlogging, frost resistance, wound healing, and resistance to pathogens.
4. Improves fruit quality. Spraying during the fruit expansion period can help preserve and strengthen fruit, promote fruit expansion, improve fruit quality, increase color, and enhance taste.
5. Regulate balanced crop growth. Potassium dihydrogen phosphate acts as a regulator, promoting flower bud differentiation, increasing the number of flowers, strengthening flower buds, strengthening flowers and preserving fruit, and improving fruit set. It also effectively promotes root growth and development.
