10-10-10 Controlled-Release Fertilizer Description
Risso® 10-10-10 Controlled-Release Fertilizer (CRF) is a premium-grade, polymer-coated NPK formulation engineered for consistent, season-long nutrient release. With a balanced ratio of 10% Nitrogen (N), 10% Phosphorus (P₂O₅), and 10% Potassium (K₂O), it provides uniform nutrition that supports all major growth stages—from root development and vegetative growth to flowering and fruiting.
Our advanced coating technology allows nutrients to release gradually over 30, 60, or 90 days, based on soil temperature and moisture, making it ideal for field crops, vegetables, fruits, turfgrass, and ornamental plants.
Key Benefits
Balanced NPK (10-10-10): Supports comprehensive plant health—encouraging strong roots, lush foliage, and quality yields.
Controlled Nutrient Release: Coated granules release nutrients in sync with plant demand, reducing leaching and volatilization losses.
Higher Nutrient Use Efficiency (NUE): Improves fertilizer uptake efficiency by up to 50% compared to conventional fertilizers.
Fewer Applications: Extended-release profile lowers labor and input frequency—saving time and cost.
Eco-Friendly: Reduces nutrient runoff and groundwater contamination, aligning with global sustainability standards.
Recommended Use
Suitable for:
Vegetables, fruits, ornamentals, turfgrass, nurseries, greenhouse crops, and landscaping.
Application Guidelines:
Field Crops & Vegetables: 50–150 kg/ha depending on soil analysis
Turf & Lawns: 3–5 kg per 100 m²
Container Plants: 1–5 g per liter of growing media
Method:
Broadcast evenly or apply as base dressing. Light irrigation is recommended after application to activate nutrient release.
