Prayon launches Calcium Nitrate EXTRA
Engis, 20th December 2016 – 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).
Less water is more calcium
Prayon’s Calcium Nitrate EXTRA is highly concentrated and perfectly soluble in water. Compared to
standard calcium nitrate fertilisers, the calcium content has been boosted by 25% to 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”, explains 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.”
Ideal alternative to liquid calcium nitrate
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 fertilisers 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 fertiliser 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
fertilisers for horticultural uses. Calcium Nitrate EXTRA will be distributed worldwide by Prayon, which
has exclusive rights for the Benelux region. As part of its customer support, Prayon is offering to
recalculate growers’ irrigation recipes in order to demonstrate the financial and technical benefits of
Calcium Nitrate EXTRA.
