Summary
This review, published in Frontiers in Plant Science, synthesises evidence on improving nitrogen use efficiency (NUE) in agricultural systems by combining agronomic interventions with advances in plant genetics and breeding. It likely examines how practices such as optimised fertiliser application, soil management, and crop rotation interact with genetic traits governing root architecture, nitrogen assimilation, and remobilisation. The paper appears to offer an integrated framework intended to reduce nitrogen losses to the environment while maintaining or improving crop productivity.
UK applicability
Whilst the review is international in scope, its findings are broadly applicable to UK arable farming, where improving NUE is a key objective under the Farming Rules for Water, nitrate vulnerable zone regulations, and the drive to reduce synthetic fertiliser dependency under post-Brexit agricultural policy.
Key measures
Nitrogen use efficiency (NUE, %); nitrogen uptake efficiency; nitrogen utilisation efficiency; crop yield; agronomic nitrogen use efficiency (kg grain per kg N applied)
Outcomes reported
The paper likely reviews how combinations of agronomic management (e.g. fertiliser timing, placement, cover cropping) and genetic approaches (e.g. breeding for nitrogen-efficient cultivars, root architecture traits) can improve the proportion of applied or available nitrogen taken up and utilised by crops. It probably reports on nitrogen use efficiency metrics across multiple crop systems and identifies best-practice integration strategies.
