POTASSIUM THIOSULFATE is a fertilizer in solution with a high title in potassium (25% K2O) and sulfur (42% SO3) that, thanks to the original synthesis process, combines the fertilizing function of potassium with a series of properties not found in other potassic fertilizers:- thanks to the action of the thiosulfate anion, a moderate inhibitor of nitrification and urease processes, it makes it possible to significantly reduce nitrogen losses by volatilization and leaching;- it increases the degree of assimilability of phosphates by virtue of the reducing and acidifying action carried out in the soil layers explored by the roots;- provides considerable proportions of elemental sulfur (fertilizing and corrective action);- protects microelements such as iron and manganese from insolubilization phenomena, reducing manifestations of chlorosis and micro deficiencies. EURO TSA's special formulation of POTASSIUM THIOSULPHATE, due to its total absence of chlorine, is particularly suitable for use in fertigation on horticultural crops and for foliar applications on fruit crops and vines.
