30days~360days Polymer Coated Fertilizer(PCF) Coated DAP 17-45-0 ~ 16-43-0 Controlled Release Fertilizer

short description:

Polymer Coated DAP (PCF) – Precision Phosphorus & Nitrogen Delivery

Polymer Coated DAP (PCF) redefines efficiency for phosphorus and nitrogen fertilization in bulk agricultural applications. Utilizing advanced polymer encapsulation technology, each 17-45-0 to 16-43-0 granule releases nutrients predictably over 30–360 days, synchronized with crop demand. The semi-permeable coating reacts to soil moisture and temperature, gradually solubilizing the diammonium phosphate core to minimize fixation in acidic/alkaline soils while reducing ammonia volatilization and phosphate runoff by 45–60%. Ideal for single-application programs, PCF eliminates top-dressing needs for crops like cereals, oilseeds, and turf, cutting labor costs by 30% and boosting phosphorus efficiency by 50% versus conventional DAP. Its dust-free, high-strength granules ensure seamless blending with other fertilizers and smooth bulk handling in big bags or hopper trucks. Customize NPK grades, release curves (linear/sigmoid), and durations to match specific soil profiles and crop cycles. Optimize yields sustainably—contact us for bulk pricing and agronomic support.
