Potassium Phosphite Solution
Potassium Phosphite Solution: Our Product Information
Risso® Potassium Phosphite Solution (0-35-55) is a high-purity, fully water-soluble PK liquid fertilizer supplying readily available phosphite phosphorus (P³⁺) and potassium (K). It ensures fast absorption, efficient nutrient utilization, and stable crop performance. With no export restrictions, it is ideal for global agricultural supply.
- ✅ Rapid Uptake & Enhanced Plant Resistance
Supports quick absorption through leaves and roots, improves nutrient use efficiency (NUE), and enhances plant tolerance to stress and disease. - ✅ Concentrated Liquid for Precision Application
High-content liquid formulation (P₂O₅ 500–525 g/L, K₂O 270–340 g/L), optimized for fertigation and foliar use, ensuring easy application and consistent results.
Product Overview
Potassium Phosphite Liquid (K₂HPO₃) is a high-purity liquid phosphorus–potassium fertilizer formulated for rapid plant uptake and advanced crop nutrition. As a fully water-soluble liquid, it is specifically designed for fertigation systems, foliar application, and precision agriculture, ensuring uniform distribution and immediate availability of nutrients.
Unlike conventional phosphate fertilizers, potassium phosphite contains phosphorus in the phosphite form (P³⁺), enabling faster absorption, superior mobility, and enhanced physiological activity within plants.
