Nitrogen use efficiency

Reductions in nitrogen use efficiency (NUE) are determined by a number of factors, including N leaching, losses of N from the soil as gas and crop diseases. Given the current seasonal conditions, how can nitrogen inputs be optimised for the 2018 growing season? There are more than 50 trials in OFT that contain results on NUE and address a number of topics, including soil water interactions, N source and placement, topdressing and soil-specific N strategies. For further information on improving NUE, go to:
