Iron granule with 30% So3 and MgO 2%




IRONSPHERE is a fertilizer specially designed to provide Iron, Sulphur, and Magnesium in an easily available form. The Sulphur acidifies the soil and improves its structure hence permitting the maintenance of the iron and the other microelements in the most available forms. The iron immediately available prevents and cures any iron chlorosis. The magnesium reacts in a synergic action in the greening of all plants. The formulation in granular form renders the applications very simple. Besides, the product prevents and cures against the formation of moss. Manganese and zinc are added to the fertilizer. IRONSPHERE may be implied as an anti-feeding action against snails.
