Potassium Dihydrogen Phosphate for Agricultural Purposes
1. Replenish Your Nutrients
Potassium dihydrogen phosphate is a high-quality phosphate and potassium fertilizer that promotes the absorption of nitrogen and phosphorus by crops, quickly supplements phosphorus, and increases crop yield and 1000-grain weight. It is suitable for a variety of crops including wheat, rice, cucumber, tomato, and grape, significantly improving crop growth effectiveness.
2. Improve Resilience
Potassium dihydrogen phosphate enhances crop resistance, including drought resistance, dry heat resistance, waterlogging resistance, freezing resistance, damage and healing resistance, and bacterial infection resistance. These properties make it particularly valuable in agricultural production, especially in harsh environments where it protects crops from adverse effects.
3. Promote Crop Growth
Spraying potassium dihydrogen phosphate during the fruit expansion stage protects and strengthens fruit, promotes expansion, improves quality and color, and enhances taste. It also promotes flower bud differentiation, increases flower quantity, encourages bud formation, and improves fruit setting rate.
