Calcium nitrate is mainly produced as a fertilizer, used for plant nutrition purposes, and for wastewater treatment. It is a source of both calcium and nitrogen, for plants.

Nitrogen is a macro element, required by plants in large quantities. It is a building block of the chlorophyll and of amino acids.

Calcium is an important component of the cell walls and proper supply of calcium is essential to plant development. It improves fruit quality, shelf life, strengthens the cell wall and helps to protect the plant from stress and diseases.

Calcium moves in plants only up from the roots, with the water flow, and is immobile once incorporated in plant tissue. Therefore, a constant supply is required.
