NPK 15‑15‑15 – 30-Day Controlled-Release Fertilizer
Balanced 30-Day Nutrient Release for Horticultural, Vegetable, and Greenhouse Crops
NPK 15‑5‑15 – 30-Day Controlled-Release Fertilizer
Nitrogen (N) 15% – supports vigorous vegetative growth and overall plant vigor.
Phosphorus Pentoxide (P₂O₅) 15% – promotes strong root development and early crop establishment.
Potassium Oxide (K₂O) 15% – enhances stress tolerance, improves fruit and grain quality, and supports water-use efficiency.
30‑Day Controlled Release: Polymer coating ensures steady nutrient supply for ~30 days, reduces losses, and minimizes the need for repeated application.
