NPK 6-25-19 Controlled Release Fertilizer is a high-efficiency polymer-coated granular fertilizer designed for sustained nutrient release. With a nutrient composition of 6% nitrogen, 25% phosphorus, and 19% potassium, this product is engineered to meet the nutritional needs of crops during critical rooting, flowering, and fruiting stages. Manufactured using High Tower Granulation Technology, it ensures uniform granule size and enhanced release control, improving plant growth while reducing labor and input costs.
Polymer Coated Surface
The outer layer is engineered for slow and precise nutrient release based on environmental conditions.
Controlled Nutrient Delivery
Nutrients are released steadily over 1–3 months, minimizing leaching and maximizing uptake.
Uniform Core Granules
Produced using compound granulation for consistent shape, color, and nutrient content.
Flexible Longevity
Available in 30, 60, or 90-day formulations to match crop cycles and climate conditions.
Labor & Cost Saving
A single application per season reduces fertilization frequency and operational input.
Eco-Friendly Design
Reduces nutrient runoff and supports sustainable farming practices.
This fertilizer is ideal for crops requiring high phosphorus and potassium levels, particularly in stages where root growth, flowering, and fruit setting are critical.
Recommended Crop Types:
Vegetables: Tomatoes, peppers, carrots, lettuce, cucumbers
Fruits: Citrus, berries, apples
Flowers & Ornamentals: Roses, tulips, marigolds
Field Crops: Corn, wheat, soybeans, rice
Lawns & Turf: Residential gardens, golf courses, sports fields, parks
Pre-Planting: Incorporate into soil a few inches deep before sowing for optimal nutrient distribution.
During Growth: Apply around the root zone or in furrows without disturbing roots.
Method: Suitable for broadcasting, furrow application, or fertigation.
Best Practices:
Ensure even application to avoid over-concentration.
Water after application to activate the release mechanism.
Consult agronomists or soil testing results for a tailored fertilization plan.
Note: No fixed dosage is provided. Usage should be determined based on local conditions, crop needs, and soil analysis.
