Medium Long-Term CR (90 Days) Detailed Specifications
Terafon® 90-Day Controlled-Release NPK is developed to provide stable, predictable nutrient release that matches plant growth curves across a wide range of cropping systems. Its polymer coating regulates diffusion based on soil temperature and moisture, supplying essential nutrients gradually and efficiently. This controlled delivery reduces fertilizer waste, enhances root-zone nutrient availability, and minimizes labor associated with multiple fertilization events. The product is especially suited for crops requiring consistent nutritional support over 2–3 months.

Key Agronomic Advantages
-
Continuous 3-Month Feeding: A single application provides consistent nutrient availability for ~90 days, reducing labor and maintaining steady vegetative and reproductive growth.
-
Enhanced Nutrient Use Efficiency: Controlled release minimizes leaching and volatilization, improving fertilizer ROI and supporting more sustainable nutrient management.
-
Uniform Growth & Better Crop Quality: Stable NPK supply promotes even canopy development, stronger root systems, improved fruit set, and increased overall crop uniformity.
-
Suitability for Diverse Crops: Ideal for greenhouse crops, nursery plants, fruiting vegetables, perennial ornamentals, berries, turf, and landscaping applications.
- Supports Sustainable Farming Practices: Reduced application frequency, lower nutrient losses, and improved soil-environment interaction make it suitable for eco-focused growers.
Recommended Applications
-
Greenhouse & Nursery Production: Ensures consistent nutrition in controlled environments and potting media.
-
Vegetables & Fruiting Crops: Tomatoes, peppers, melons, and mid-season vegetables needing stable nutrient supply.
-
Ornamentals & Landscape Plants: Shrubs, ornamentals, perennials, and flowering plants.
- Specialty Crops: Berry crops, turfgrass, and horticultural crops benefiting from extended nutrient availability.
Application Guidelines
-
Perform soil or substrate testing to determine crop nutrient demand.
-
Apply at planting or early growth for best synchronization with the crop cycle.
-
Broadcast, band, or mix into media, depending on cropping system.
-
Irrigate after application to activate controlled nutrient diffusion.
- Adjust application rates according to crop species, soil fertility, and growth targets.
