What is Calcium Nitrate?
Calcium Nitrate (Ca(NO3)2) is a highly water-soluble inorganic salt that provides both calcium and nitrate nitrogen, two essential nutrients for plant growth. It is a white to off-white, highly hygroscopic crystalline or granular material that readily dissolves in water, making it one of the most efficient and fast-acting calcium and nitrogen fertilisers available, particularly valued for its use in fertigation and hydroponic systems.
Polychem Industries supplies Calcium Nitrate in fertiliser grade and industrial grade to agricultural input companies, hydroponic system suppliers, and the construction and water treatment industries across India and internationally. Its dual nutrient function and complete water solubility make it a preferred choice for high-value crop production, while its calcium content also finds use in concrete admixture applications.
Available Grades
| Grade | Form | Purity | Standard | Applications |
|---|---|---|---|---|
| Fertiliser Grade | White to off-white granules/prills | 98%+ (Fertiliser Grade) | Fertiliser Standard | Fertigation, hydroponics, horticulture |
| Industrial Grade | White crystalline solid | 98% | Industrial | Concrete admixtures, water treatment, explosives industry |
Applications & Uses
Fertigation & Hydroponics
The primary application. Calcium Nitrate is widely used in fertigation (fertilising through irrigation systems) and hydroponic nutrient solutions due to its complete water solubility and provision of both calcium and nitrate nitrogen in immediately plant-available form.
Fruiting Vegetable Crops
Particularly valued in tomato, pepper, and other fruiting vegetable production to prevent calcium-deficiency disorders such as blossom end rot, while simultaneously supplying nitrogen for vegetative growth.
Fruit Tree & Orchard Nutrition
Used in orchard fertigation programs to supply calcium, which is important for fruit firmness, storage quality, and reducing physiological disorders in apples, pears, and other fruit crops.
Concrete Admixtures
Industrial Grade Calcium Nitrate is used as an accelerating admixture in concrete, speeding up the setting and hardening process, which is particularly valuable in cold weather concrete applications.
Water Treatment
Used in certain water and wastewater treatment applications, including odour control in sewage systems where it helps prevent the formation of hydrogen sulphide gas through biological nitrate reduction processes.
Industrial & Chemical Applications
Used as a raw material and oxidising component in various industrial chemical processes, including certain explosive formulations and other specialty chemical manufacturing applications.
