Poly Sal – is an aqueous solution of polymaleic acid; if it’s integrated into the soil, it solubilizes the calcium, magnesium and sodium; the first two replace sodium at the myceliums, keeping the last one available to be leached by the irrigation water.
Sonar Sal – adds to the soil water soluble calcium and organic acids, in soluble and stable form, drastically reducing the ‘’toxic’’ level of complex colloidal sodium.
