The Prayon Group, a world leader in the phosphates sector, has added a new product to its Hortipray® range of fertilisers: Calcium Nitrate EXTRA (17 - 0 - 0 + 33% CaO).
The new Calcium Nitrate EXTRA is highly concentrated and perfectly soluble in water. Compared to standard calcium nitrate fertilizers, the calcium content has been boosted by 25 – 33% calcium oxide (CaO). It also guarantees that at least 17% nitrogen will be available as nitrates.
“Compared to standard products, the crystals in Calcium Nitrate EXTRA contain fewer water molecules, resulting in a higher concentration of nutrients”, explained Kurt Verhelst, Prayon Northern Europe Horticulture Customers Coordinator. “The more concentrated product helps growers reduce their transport and storage costs. Specifically, five bags of standard fertiliser can be replaced by four bags of Calcium Nitrate EXTRA while maintaining the same amount of readily available calcium.”
The new Hortipray® product is free of impurities, such as sodium and other unwanted particles, and contains a negligible amount of ammonium, unlike the calcium nitrate fertilizers typically used.
“In some hydroponic crops, excessive ammonium can cause growing problems resulting in yield and quality losses. It is mainly for this reason that a liquid version of calcium nitrate – containing no ammonium – has been introduced into modern horticulture. Calcium Nitrate EXTRA is the perfect solid alternative to this liquid calcium nitrate.”
In cases where ammonia is desired and added to the irrigation water, Prayon can also offer cheaper alternatives and possibilities. In hydroponics, monopotassium phosphate (MKP) can be replaced by monoammonium phosphate (MAP), resulting in a cheaper complete fertilizer package without changing the nutrient availability for plants.
By extending its Hortipray® range of products, Prayon aims to offer a full range of water-soluble fertilizers for horticultural uses. Calcium Nitrate EXTRA will be distributed globally by Prayon, which has exclusive rights for the Benelux region.
