New Trials Based Evidence
Historic trials conducted by NIAB/TAG (then Morley Research Centre), concluded that applying NPKS compound fertiliser in the spring, increased yield on average by 0.3t/ha in winter wheat and barley.
This work has been repeated at the Royal Agricultural University in Cirencester and the new data has shown the benefits can be a 0.65t/ha yield increase, worth around £75/ha, based on Sept 2016 cereals prices. See below for further information on this latest R&D.
Even if you include the cost of fertiliser, the financial advantage to using spring applied Heartland Sulphur is still an average of £65/ha.
