Abstract
One of the basis water-soluble fertilizers that are used in greenhouse enterprises is a Calcium nitrate, where its production and demand raise. At present time, calcium nitrate is produced in a granulated and crystaline form consisted of tetrahydrate, dihydrate and concentrated variants. These forms are significantly distinguished by their chemical composition. Besides the basic form of nitrogen – nitrate – there is ammoniacal nitrogen in the composition of Calcium nitrate that is found to be undesirable element, particularly with drip irrigation system in the greenhouse. The new product, calcium nitrate has been worked out with minimal content of ammoniacal nitrogen at URALCHIM. The study showed the advantages of the product for such characteristics as solubility and time of dissolving. It dissolves 3.4-7 time faster than those of tetrahydrate and dihydrate analogues. At present time, the concentrated calcium nitrate is used in many greenhouse industrial complexes and enterprises, and has shown its efficiency in practice.
