Calcium Nitrate
Calcium nitrate, also called Norgessalpeter (Norwegian saltpeter) is the inorganic compound with the formula Ca(NO3)2 4H20. This colourless monoclinic crystal absorbs moisture from the air and is commonly found as a tetrahydrate. Calcium nitrate is manufactured by neutralising nitric acid with calcium carbonate. It is mainly used as a component in fertilizers.

Uses For Calcium Nitrate
- Commonly used in fertilizer See below for more information
- Used as a plant food
- Corrosion inhibitor in diesel fuel
- Used in manufacture of matches & fireworks
Calcium nitrate is mainly used as coagulant in rubber latex manufacture and asa refrigerant. It is also used in oil exploratory well and sewage treatment. In agriculture it is used as soiless culture and fast-effective fertilizer for acid soil. It also can be used to make fireworks and incandescent lamp chimney in light industry, to produce explosives in national defense industry and to paint negative pole in electron instrument industry. It is also a raw material in making other nitrates.
Calcium Nitrate as a fertiliser
calcium nitrate is used as a fertiliser as it increases yield and quality of fruit and crops, it builds up resistance to disease and pests, it extends the storage life of fruits, it permits rapid absorption of calcium and nitrate by plants, it does not burn and it doesn’t create alkaline or salt conditions. Calcium nitrate provides 15.5% nitrogen and 26.3% calcium which can be rapidly absorbed by plants.
The use of Calcium Nitrate in saline soils, maintains high calcium levels
which will reduce the plants uptake of sodium resulting in improved plant
growth. Improved soil structure: The calcium in Calcium Nitrate displaces sodium
in the soil profile, which improves soil structure increasing water and oxygen
infiltration in sodic soils.
Improved disease tolerance: Calcium strengthens the plants cells and improves
disease tolerance. Low calcium cells are weak with lower resistance to disease
invasion and a tendency to leak nutrient from the cell provides a ready source
of food source for disease to develop. Examples of this include: Botrytis in
roses, lettuces, stone fruit and clubroot in brassicas.
Applications of calcium nitrate also improve the storage quality of crops
reducing bitter pit in apples, bulb rot in onions and Erwinia soft rot in
potatoes; it permits longer shelf life of table grapes, stone fruit and fresh
flowers. Other benefits of feeding with calcium nitrate include improved skin
and peel appearance with reduced blemishes and improved stress tolerence.
Ground application: 125 to 250 kg/ha. Up to
3 applications per season depending on crop.
Foliar application: 500 to 800 grams per 100 litres. Up to
10 applications per season depending on crop.
Hydroponic solutions: Run at 1 gram per litre of water flowing
through the system.
