Key Features & Agronomic Advantages
120-Day Controlled Release: Predictable, sustained release curve aligned with crop uptake to support long-cycle crop development.
High-Efficiency Polymer Coating: Temperature-responsive diffusion reduces leaching, volatilization, and runoff for higher nutrient-use efficiency (NUE).
Balanced Nutrient Delivery: Available in precise NPK ratios such as 14-14-14, 15-15-15, 16-8-24, 20-20-20, with optional secondary and micronutrients.
Uniform Granule Size (2–4 mm): Ensures accurate broadcasting, banding, or incorporation with consistent nutrient distribution.
Enhanced Crop Performance: Promotes continuous vegetative growth, optimized fruiting, and improved root vigor over the entire season.
- Reduced Labor & Inputs: Single-application fertilization lowers operational cost and supports sustainable farming practices.
Recommended Applications
Orchards & Vineyards: Long-season fruit trees, grapes, citrus
Greenhouse & Nursery: Container plants, ornamentals, landscape plants
Field Crops (Long Cycle): Oilseeds, cereals, specialty crops
Turf & Sports Fields: Season-long nutrient maintenance
- High-Value Horticulture: Berries, perennials, long-term vegetables
Application Guidelines
Conduct soil analysis before application to determine baseline nutrient demand.
Apply at planting or early development for best season-long performance.
Light irrigation after application improves coating activation.
In warm climates, anticipate slightly accelerated release—adjust timing accordingly.
- Usually one application per season is sufficient; supplement only if tissue analysis indicates deficiency.
Packaging & Storage
Packaging: 25 kg / 50 kg woven PP bags, 500–1,000 kg jumbo bags
Storage: Store in a cool, dry, ventilated warehouse; protect from moisture and direct sunlight
