Agricultural Applications
1. Nutrient Replenishment
Potassium dihydrogen phosphate is a high-quality phosphate and potassium fertilizer that promotes nitrogen and phosphorus absorption in crops. It quickly supplements phosphorus, increasing crop yield and 1000-grain weight. Suitable for various crops including wheat, rice, cucumber, tomato, and grape, it significantly improves crop growth effectiveness.
2. Enhanced Resilience
This compound strengthens crop resistance to environmental stresses including drought, dry heat, waterlogging, freezing, and bacterial infections. These properties make it particularly valuable in harsh growing conditions where crop protection is essential.
