ForFarmers has released a new fertiliser offering, the TopFert range, containing polysulphate, a multi-nutrient fertiliser made up of sulphur, potassium, calcium and magnesium.

Polysulphate is a 2mm to 4mm granular product with good binding and spreading characteristics, available in both water-soluble and plant-available forms. With a prolonged release rate of sulphate to match crop uptake and reduce leaching risk, it is low in chloride so ideal for chloride-sensitive crops.

 Sourced in the UK, the TopFert range includes blends for all crop requirements including reseeding, grazing and cutting.

 Paul Coupe, ForFarmers' Fertiliser Product Manager, says: "TopFert Reseed is an ammonium nitrate-based product with seven units of sulphur for grass and clover establishment. It also contains enhanced phosphate to ensure it remains available to the plant. The high phosphate inclusion also supports an increase in root mass, which is critical for plant establishment."

 There are two TopFert grazing blends. TopFert Graze includes OEN a dual-action nitrogen protector to minimise losses through volatilisation, leaching and nitrification. It also includes sodium, calcium and sulphur which is supplied from polysulphate.

 As an alternative, TopFert GrazePluS is AN based and has the addition of phosphate, as well as sodium, calcium and sulphur. The sustained release of sulphur improves nitrogen efficiency and plant protein levels.

 The final blend in the range is TopFert Cutting, which also contains a dual-action nitrogen protector. The addition of sodium increased grass palatability and intake, and improves utilisation, while the calcium improves plant cell-wall strength.

 Paul says: "Other nutrients can be added to the range as required. For example 90% of soils in the UK are deficient in selenium levels and this nutrient should be applied little and often. Low levels of magnesium can result in grass staggers and, although often added to compound feed, this trace element can also be added to fertiliser."

 ForFarmers recommends regular soil and slurry analysis before purchasing bagged fertiliser so blends can be adjusted to suit specific requirements.
