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.
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.

Farm-centric research generally involves On-Farm Experimentation and may be better described as 'Farm Action Research', i.e. research conducted at least in part by and for beneficiaries who also farm.
On Farm Experimentation (OFE) is increasingly being recognised as having transformative power in improving performance in agricultural systems across the world.
