Calcium Nitrate Boron
About Calcium Nitrate Boron
Calcium Nitrate Boron Fertilizer for Fruit Set and Quality
Calcium Nitrate Boron is a water-soluble fertilizer combining 15.5% N, 19% Ca, and 0.2-0.3% B, designed for fruits, vegetables, and brassicas to prevent deficiencies and enhance cell wall strength.
Calcium builds sturdy tissues and reduces disorders like blossom end rot, boron supports flowering, pollination, and fruit set, while nitrate nitrogen promotes rapid growth, leading to 10-15% yield increases and firmer produce.
It improves nutrient uptake, stress tolerance, and storage longevity without raising soil pH.
