Typical yield losses from nitrogen source


Replicated trials carried out independently on behalf of Yara showed an average 5% yield loss from using urea compared to ammonium nitrate when applied at the 225 kg N/ha rate in winter wheat. Read more on the effect of N source on yield

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.

Sulphur: Best Practice
It is widely accepted that UK soils are deficient in sulphur so supplementation via organic manures or mineral fertilisers is essential. What I think is less understood is that not all sulphur-containing fertilisers are the same.
