12-6-36 Controlled-Release Fertilizer Description
Risso® 12‑6‑36 Controlled-Release Fertilizer is a high-performance, potassium-rich controlled-release fertilizer engineered for intensive fruiting and flowering crops. This advanced NPK formulation supports optimal crop development by synchronizing nutrient release with plant uptake, reducing leaching and maximizing nutrient use efficiency.
Key Technical Advantages
Balanced Nutrient Supply:
12% total nitrogen (nitrate + ammonium), 6% phosphorus, and 36% potassium for enhanced fruit formation, sugar translocation, and crop resilience.Advanced Controlled-Release Technology:
Encapsulated with a polymer coating for consistent nutrient release over 3 to 12 months, matching crop demand throughout the growth cycle.Enriched with Essential Micronutrients:
Fortified with magnesium (Mg), sulfur (S), and trace elements including boron (B), zinc (Zn), iron (Fe), manganese (Mn), copper (Cu), and molybdenum (Mo) to ensure complete plant nutrition.Improves Crop Quality & Yield:
Promotes uniform fruit size, better coloration, higher Brix values (sugar content), and increased shelf life—ideal for fruits, vegetables, ornamentals, and greenhouse crops.Environmentally Smart:
Reduces nitrate leaching, volatilization, and denitrification losses—contributing to more sustainable agriculture practices.
