The Dissolvine® X line contains microgranular iron chelates and is developed for the correction and prevention of iron deficiency in a wide range of agricultural and horticultural crops. Particularly in alkaline and calcareous soils.

Dissolvine X products are most effective when applied dissolved to the plants through the soil or rooting media. The number in the product name reflects the so-called 'ortho-ortho' level which is a measurement for quality and a label requirement in the European Union. Scientific research has proven that the ortho-ortho isomer is the only isomer which performs in soils, particularly in calcareous soils. Nouryon uses the official CEN methods to express the ortho-ortho, and if applicable also the ortho-para levels on our product labels.

The Dissolvine X line contains 60 grams of chelated iron per kg of product. HBED is an abbreviation of di ortho- (HydroxyBenzyl Ethylenediamine Diacetic) acid. This 'di ortho' reflects the ortho-ortho isomer. The table shows our available products. Nouryon has the widest range of Fe EDDHA and Fe HBED products in the world.
