TIO-K Active and TIO-N Active contain sulphur as the thiosulphate ion. This ion has a strong reducing activity towards all the microelements and in particular iron and manganese. Microelements, already contained in the soil or supplied through specific treatments, are quickly oxidised becoming unavailable to the root system. Treatments with thiosulphates can reduce metal oxides making them available for the crop. Tests carried out show that after treatment symptoms of iron chlorosis have been overcome.
Ferric ions (Fe3+) are present in the soil but unavailable to the plant: treatment with thiosulphate ion reduces the iron to ferrous ions (Fe2+) which are readily absorbed by the crop.
ACTIVATORS are available in two different formulations: ammonium thiosulphate and potassium thiosulphate.
