As part of the AICC Crop Nutrition Club 2022, this simple on-farm winter wheat trial in Nottinghamshire tested the yield effect of reducing N rate from the 'farm standard' of 220 kg/ha to 170 kg/ha. The trial was facilitated by a local AICC advisor, with support and reporting from ADAS.
Results summary: reducing the N rate from the farm standard rate of 220 to 170 kg/ha reduced yield by 0.6 t/ha and gross margin by about £70, according to grain and fertiliser prices from autumn 2022.
