10-20-10 Controlled-Release Fertilizer Description
Risso® 10‑20‑10 Controlled-Release Fertilizer (CRF) is a high-phosphorus polymer-coated fertilizer delivering 10% Nitrogen (N), 20% Phosphorus (P₂O₅), and 10% Potassium (K₂O). Designed specifically to promote strong root establishment and early plant development, this fertilizer is ideal for crops with high phosphorus demands such as root vegetables, fruiting crops, and young seedlings.
Using advanced polymer encapsulation, Risso® 10‑20‑10 CRF ensures steady nutrient release over 60 to 90 days, adapting to soil temperature and moisture conditions. This controlled-release mechanism reduces nutrient loss and enhances fertilizer efficiency, supporting sustainable agricultural practices globally.
Key Technical Advantages
High Phosphorus Content: Supports robust root growth and early crop establishment.
Balanced N and K: Provides essential nitrogen and potassium for overall plant health and stress tolerance.
Polymer Coating Technology: Enables temperature- and moisture-responsive nutrient release, minimizing leaching and volatilization.
Extended Release Duration: Ensures consistent nutrition during critical growth stages, reducing the frequency of fertilizer applications.
Low Chloride & Heavy Metal Content: Safe for sensitive crops and compliant with international environmental standards.
