Product Overview

Full NPK Controlled-Release Fertilizer is formulated to deliver balanced macro-nutrients over ~120 days, ensuring long-term nutrient stability in the root zone. Its coating structure enables controlled diffusion driven by environmental conditions, supporting sustained crop growth without nutrient interruption.

Only N Controlled-Release Fertilizer focuses on extended nitrogen availability, improving nitrogen efficiency and reducing volatilization or leaching losses, especially in crops with prolonged nutrient demand.

This fertilizer is ideal for perennial crops, greenhouse systems, landscaping, and other applications requiring long-lasting nutrient supply.

Scientific Benefits of 120-Day Controlled-Release NPK

1. Extended Nutrient Supply for Long Crop Cycles
The 120-day release profile ensures nutrients remain available throughout extended growth stages, reducing the risk of nutrient depletion and supporting continuous plant development.

2. Improved Nutrient Retention in Soil
Advanced coating technology helps maintain nutrients within the root zone, minimizing environmental loss and enhancing fertilizer efficiency over time.

3. Enhanced Crop Performance and Quality
Consistent nutrient delivery promotes uniform plant growth, improved root activity, better fruit development, and enhanced crop quality for high-value markets.

4. Reduced Input and Operational Costs
Longer nutrient release duration decreases the need for repeated fertilization, lowering labor, transportation, and application costs.
