A wide range of experiments are being conducted on Polysulphate by the new Israeli-based Center for Fertilization and Plant Nutrition (CFPN), located at Gilat Research Center. These trials are designed to study different aspects of Polysulphate solubility, transport in soils, and mineral uptake by plants.

The first experiment to have been concluded assessed the impact of different doses of Polysulphate on wheat, in comparison to the equivalent dose of nutrients coming from K₂SO₄, CaSO₄ and MgSO₄. The transport of sulfur (S), potassium (K), magnesium (Mg) and calcium (Ca) in the soil, and the uptake of these nutrients by wheat plants, was also assessed.

While the chemical analyses are expected soon (we will share these with you in due course) we are pleased to present visual proof of Polysulphate efficacy. Polysulphate was superior to equivalent rates of soluble sulphate sources of K, Mg and Ca; plants developed were stronger and taller with increased dry matter.

This experiment has demonstrated the full solubility and availability of Polysulphate, and confirms its effectiveness on plant growth as a source of S, K, Mg and Ca, as shown by many other experiments carried out on different crops around the world.
