180-Day Controlled-Release Fertilizer: Our Product Information

✅ Ultra Long-Release 180-Day Controlled-Release Fertilizer for Maximum Efficiency
This 180-day controlled-release fertilizer features advanced multi-phase polymer encapsulation technology, enabling ultra-long nutrient release for up to 6 months. It is specifically designed for perennial crops, plantations, and landscaping systems that require continuous nutrient availability with minimal intervention.
✅ Engineered for Long-Term Nutrient Stability
The controlled nutrient release curve is optimized to provide progressive N–P₂O₅–K₂O supply, ensuring nutrients are available throughout extended growth cycles while minimizing nutrient fluctuation and deficiency risks.
✅ Low-Input, High-Efficiency Fertilization Solution
With a significantly extended release duration, this fertilizer reduces application frequency to a minimum, helping growers lower labor, logistics, and operational costs while maintaining consistent crop performance.
Controlled-release fertilizer solutions include:
- Only N Controlled-Release Fertilizer – Ultra-long nitrogen release for sustained vegetative growth.
- Full NPK Controlled-Release Fertilizer – Complete macro-nutrient delivery for long-term crop nutrition.

Product Overview

Full NPK Controlled-Release Fertilizer provides a controlled nutrient supply over ~180 days, maintaining stable nutrient availability in the root zone for extended agricultural cycles. Its coating system regulates nutrient diffusion in response to environmental conditions, ensuring consistent feeding without nutrient shock or depletion.

Only N Controlled-Release Fertilizer is optimized for extended nitrogen efficiency, delivering nitrogen steadily over time and minimizing environmental losses, particularly in systems with long vegetative growth periods.

This product is ideal for orchards, plantations, turf management, forestry, and greenhouse applications requiring long-lasting and reliable fertilization.

Scientific Benefits of 180-Day Controlled-Release NPK

1. Ultra-Long Nutrient Supply
The 180-day release cycle ensures a continuous supply of nutrients throughout extended crop cycles, supporting uninterrupted plant development and minimizing nutrient stress.

2. Superior Nutrient Retention & Efficiency
Advanced coating systems significantly reduce nutrient loss through leaching and volatilization, improving fertilizer efficiency and environmental sustainability.

3. Consistent Crop Growth & Quality
Stable nutrient delivery supports uniform plant growth, enhances root system performance, and improves crop quality, especially in high-value and perennial crops.

4. Minimal Application Frequency
Extended release duration reduces fertilization events to one or two applications per season, lowering labor requirements and operational costs.
