12-24-12 Controlled-Release Fertilizer Description
Risso 12-24-12 Controlled-Release Fertilizer is a precision-formulated NPK blend containing 12% nitrogen, 24% phosphorus (P₂O₅), and 12% potassium (K₂O). It is designed to promote strong root development, vigorous early vegetative growth, and optimal flowering across a broad range of crops. The advanced controlled-release coating technology ensures a consistent, seasonally aligned nutrient release, significantly improving nutrient use efficiency (NUE) while reducing leaching, volatilization, and runoff.
This formulation is ideal for application at planting, transplanting, early bloom, or turf establishment, and is suitable for both field crops and high-value horticultural systems such as drip irrigation, nursery, and landscape settings.
Key Features & Agronomic Advantages
High Phosphorus Content (24%): Promotes robust root architecture, faster seedling establishment, and earlier flowering.
Balanced Nitrogen & Potassium (12‑12): Supports vegetative vigor and resilience during early growth stages.
Controlled-Release Technology: Coated with high-efficiency polymer or sulfur-compound materials to ensure sustained nutrient delivery over 30 to 90 days, depending on soil temperature and moisture.
Low Salt Index & Chloride-Free: Ideal for salt-sensitive crops and greenhouse systems.
Environmentally Responsible: Reduced nutrient loss to the environment, protecting groundwater and minimizing application frequency.
Enrichment Options Available: Can be customized with chelated micronutrients (Fe, Zn, Mn, Cu, B, Mo) or humic substances for enhanced soil fertility and plant metabolism.

Advanced Controlled-Release Technology
Risso’s CRF granules utilize a smart-release mechanism that responds to soil temperature and moisture:
Water Infiltration activates the coating.
Nutrient Diffusion occurs gradually through the coating matrix.
Synchronized Supply ensures nutrients are available when the plant needs them most.
This results in reduced labor and application frequency, and promotes sustained crop performance and higher yields.
Packaging & Customization
Standard Pack Sizes: 9.5kg, 25 kg PE-lined woven bags, 500 kg jumbo bags
Custom Services: OEM/ODM labeling, tailored NPK ratios, coating duration, micronutrient enrichment, and color coding for granules
Certifications: ISO 9001, ISO 14001, REACH compliance; RoHS and heavy metal limits upon request
