It is a white, crystalline, solid calcium and nitrogen fertilizer with high moisture absorption. It contains 15.5% nitrogen (14.2% nitrate nitrogen, 1.3% ammonium nitrogen) and 26% calcium (CaO). It is obtained by reacting ground limestone with nitric acid. Since it is completely soluble in water, in addition to classical uses, it can be applied to the soil with drip/sprinkler/underground infiltration irrigation and to the leaves with a sprayer.
