Fruit & vine growers can address yield-sapping nutrient deficiencies

ICL is making its increasingly popular low carbon footprint, multi-nutrient fertiliser polysulphate (48% SO₃, 14% K₂O, 17% CaO and 6% MgO) available to fruit and vine producers in a special ‘Mini Granular’ formulation packed in simple to manage 25Kg bags.

As sulphur and other key nutrient deficiencies increase across the UK and growers seek sustainable methods for boosting soil fertility, the new format could bring the benefits of polysulphate to a much wider range of producers, says ICL’s Andrew Judd.

“Mined in North Yorkshire, polysulphate is a natural product with the lowest carbon footprint of any fertiliser at 0.0029kg CO₂e/kg product, making it an ideal choice for growers looking to decarbonise their production.

“It’s been proven to lift yields and improve crop quality significantly in a wide range of crops including in top fruit and grape production.

“Polysulphate is approved by the Soil Association and Organic Farmers and Growers, plus it is a perfect fit for growers following the Sustainable Wines of Great Britain (SWGB) certification scheme.”

Applied at a recommended 50g/m² (500kg/ha) to top fruit and vineyards by hand, domestic spreaders or tractor mounted equipment, polysulphate provides four essential water-soluble nutrients in a single application, he explains.

“The slow release potassium, magnesium and calcium in polysulphate will be of significant interest to wine grape growers. Particularly potassium, as this is essential  for fruit quality and sugar development and vines use about 3kg of potassium for every tonne of grapes harvested.”

Leading crop production company Agrii will be working with ICL to make the new Mini Granular product available to fruit and vine growers across the country.

“Agrii fruit agronomists use polysulphate in many forms when advising nutrient management plans for our wine grape growing customers and top fruit customers,” says Agrii agronomist Matt Greep.

“Be it Potash Plus or Agrii Fruit 50 – the Polysulphate component is perfectly balanced for fruit crops that have a high potassium requirement for yield and quality of the crop.

“This bespoke mini-granule Polysulphate in a 25kg bag is going to help vineyards of all scales make a more targeted and sustainable approach to the fertilisation of their grapes.”

Agrii has seen many crops benefiting from polysulphate in both trials and on-farm, he adds

“Polysulphate brings large amounts of sulphur to depleted soils, safely and efficiently with its mineral nature providing phased release of all of its four nutrients throughout growing season.

“The fact that it’s a 100% soluble organic fertiliser and has no effect on soil pH with all the potassium in the product being potassium sulphate with no chloride in its granule, is a real bonus for fruit and vine producers.”
