32-8-16 Controlled-Release Fertilizer Description
Risso® 32‑8‑16 Controlled-Release Fertilizer (CRF) is a premium polymer-coated fertilizer delivering 32% Nitrogen (N), 8% Phosphorus (P₂O₅), and 16% Potassium (K₂O). Designed for crops requiring high nitrogen input during rapid vegetative growth phases, this formulation supports strong root and shoot development while maintaining balanced phosphorus and potassium supply.
Advanced polymer encapsulation provides a steady, temperature- and moisture-responsive nutrient release lasting 60 to 120 days, improving nutrient use efficiency and reducing environmental impact worldwide.
Key Technical Advantages
High Nitrogen Concentration: Supports vigorous vegetative growth for cereals, vegetables, turfgrass, and ornamentals.
Balanced P and K: Supplies essential phosphorus and potassium for root development and stress resistance.
Controlled-Release Polymer Coating: Ensures gradual nutrient availability aligned with crop uptake, minimizing losses via leaching or volatilization.
Extended Release Duration: Provides consistent nutrition through critical growth stages, reducing application frequency.
Low Chloride & Heavy Metal Content: Safe for sensitive crops and compliant with international environmental regulations.
