It is an anhydrous fertilizer that is highly soluble in water. It is characterized by high concentration of the basic substance Ca(NO3)2 — 98%. It is used by many greenhouse farms for preparation of nutrient solutions for plant nutrition during the period of vegetation.

The majority of the soils contain calcium whose concentration falls within the normal range. But the calcium that is found in soils is primarily concentrated in the form that is not readily accessible to plants. Feeding with calcium is provided in the form of nitrate enables the plants to fully absorb calcium and obtain high quality fruits, increase their shelf life as this element ensures the strength of cell membranes and walls. In the absence of calcium, the growth of plants, and especially the root system, becomes weak. Calcium is necessary for the correct and healthy development of young plant tissues, increasing the hardness and quality of the fruits. Calcium nitrate prevents the development of vertex rot in tomatoes, lettuce burns, and other diseases associated with the lack of calcium.
