Since Calcium Nitrate has excellent water solubility, its highly soluble Nitrogen & Calcium are both immediately available to plants. This fertiliser can be used to correct plant deficiencies in Calcium.

Calcium Nitrate reduces blossom end rot of tomatoes & bitter lits of apples.

Calcium Nitrate contains secondary nutrient Calcium (Ca) 18.5% min & Nitrate Nitrogen (N) 14.5% min. Calcium levels in the plant directly control many enzyme reactions & enhance the uptake of Nitrate Nitrogen (N). Nitrate ions enhance the uptake of Calcium in plants. 

Calcium deficiency leads to decrease in the development of terminal shoot buds & root tips which inhibits plant growth. It also causes chlorosis & distortion of new leaves. 

Calcium is essential in cell elongation & division. Calcium also facilitates uptake of Potash (K) over Sodium (Na). Uptake of Calcium is difficult in highly leached & highly acidic soils.
