30-10-10 Controlled-Release Fertilizer Description
Risso® 30‑10‑10 Controlled-Release Fertilizer (CRF) is a high-nitrogen, polymer-coated formulation designed for steady nutrient delivery over 60 to 90 days. With 30% Nitrogen (N), 10% Phosphorus (P₂O₅), and 10% Potassium (K₂O), this fertilizer targets rapid vegetative growth, making it ideal for leafy vegetables, turfgrass, and early crop development stages.
Advanced polymer encapsulation ensures gradual, temperature-sensitive nutrient release that aligns with crop demand, reducing nutrient losses and promoting sustainable fertilization practices globally.
Key Technical Advantages
High Nitrogen Content: Supports vigorous leaf and stem growth critical for many vegetables, cereals, and turf applications.
Controlled Nutrient Release: Polymer coating regulates release rates, minimizing leaching and volatilization for efficient fertilizer use.
Long-Lasting Performance: Releases nutrients steadily over 2 to 3 months, reducing the need for frequent applications.
Improved Nutrient Use Efficiency: Enhances crop uptake and yield potential while minimizing environmental impact.
Low Chloride & Heavy Metal Levels: Safe for sensitive crops and meets international environmental standards.
