Haifa GrowClean™ - Sodium free phosphate fertilizer with cleaning effect

Haifa GrowClean™ - Sodium free phosphate fertilizer with cleaning effect

The phosphate in traditional fertilizers (such as MKP, MAP and water soluble NPK) is in the form of orthophosphate. This type of phosphate has the characteristic that it easily form a compound with calcium, magnesium and iron. As soon as this com- pound is formed it will participate in the system. It is then no longer available for the plant and can even cause blockages of the dripping system.

At a higher pH and/or a large volume of phosphate the amount of participation will increase. The result of this; less phosphate is available for the plant. An increase of phosphate does not result in improved availability for the plant because this precipita- tion reaction increases unproportionally.

After the introduction of polyphosphate many growers saw that polyphosphate in a low dosage, keeps the system clean form participation and in a higher dosage it gives extra vegetative growth to the plants. Disadvantage of the use of polyphosphates is the high pH of the product which makes it necessary to add acid in the fertilizer tank and sometimes it contains a high level of sodium.

With the introduction of Haifa GrowClean this disadvantage is a thing of the past. Haifa GrowClean contains 50 percent polyphosphate but the pH of the product is neutral. So adding acid to compensate the high pH is no longer necessary. Haifa GrowClean is sodium-free and ready and easy to use.
