Recommended nitrogen plus sulphur fertilisers

The following YaraBela fertilisers are recommended for all crops and contain nitrogen in the readily available nitrate form together with sulphur.

YaraBela AXAN
27% N + 9% SO3 - Granular uniform compound nitrate based nitrogen and sulphur fertiliser for use on all crops.
YaraBela SULPHAN
24% N + 15% SO3 - Uniform compound nitrate based nitrogen and sulphur fertiliser for use on all crops, particularly those with a higher sulphur requirement.

Fertiliser quality - don't settle for less
Soil fertility is certainly top of both farmers and policy makers minds currently, with a broad consensus that it plays a key role in the continued economic and environmental sustainability of farms.

Keeping clover in fine fettle
White clover is being increasingly used on intensively grazed farms where the benefits can be substantial, lowering both the cost of growing grass and the carbon emissions intensity of milk produced. Managing nutrient and fertiliser inputs is a key component in establishing and maintaining clover in these swards successfully.
