Grofas Polysulphate (2.5kg)

Grofas Polysulphate is naturally mined multi-nutrient fertilizer containing four fully soluble and available plant nutrients: sulphur (S), potassium (K), magnesium (Mg) and calcium (Ca). These essential nutrients can be incorporated into any finished fertilizer product or range. It has a low salt index and neutral pH with no negative effect on soil pH and electrical conductivity (EC), which allows it to be a good source of S, K, Mg and Ca including under salt stress conditions. Grofas Polysulphate fertilizer increases crop yields up to 40% while increasing profitability and reducing carbon footprint. It is also ideal for chloride-sensitive crops and organic agriculture.
