Increasing tomato crop profit with Polysulphate - a farmer’s experience from Israel

Gabay Rachamim has been farming since the 1950s, producing Ikram tomatoes from his 25 hectares of greenhouses in Israel. He shares his experiences of Polysulphate fertilizer (the new polyhalite based fertilizer from ICL Fertilizers) based on a trial carried out on his farm. The farm is supplied with desalinated water, which is lacking in calcium and magnesium. Traditionally these nutrients were supplied through multiple applications each growing season. But with Polysulphate, a single application before planting provided enough calcium and magnesium for the whole growing season. The plants without Polysulphate application showed magnesium deficiency symptoms – including yellowing of the leaves (interveinal chlorosis) in the older leaves, while the leaves where Polysulphate was applied were healthy and green. “Polysulphate saves on work time and materials – you only apply it once to the crop” says Gabay, “and time equals money, so applying Polysulphate increases my profit.” Find out more about Polysulphate fertilizer at https://www.polysulphate.com Film produced by Boaz Rabinovich
