YaraBela SULFAN (26% N + 35% SO3) is a compound nitrogen and sulphur fertiliser, also known as ASN (Ammonium Sulphate Nitrate), which is ideal for use on crops with an increased sulphur demand for example oilseed rape.

YaraBela SULFAN contains nitrogen as nitrate and ammonium. Plants require nitrogen in the ammonium and nitrate forms, so by applying these forms the nutrients are immediately available for plant growth. Nitrates are the most efficient form of nitrogen and are key to achieving optimum yields.

YaraBela SULFAN contains sulphur as ammonium sulphate which is fully soluble and immediately available for plant uptake.

YaraBela SULFAN is a homogeneous, uniform sized, high bulk density granular compound fertiliser for even spreading over wide bout widths. Being a compound fertiliser both nitrogen and sulphur are contained in every granule which eliminates segregation and allows even application of all nutrients.

Available in England, Wales and Scotland.
