How Controlled Release Technology Works
Soil moisture penetrates the coating layer.
Nutrients dissolve inside the granule.
Nutrients diffuse slowly into the soil.
Release rate adjusts naturally to temperature and moisture.
This intelligent release mechanism ensures plants receive nutrients continuously without over-fertilization or nutrient shock.
