There is real interest in variable rate nitrogen application right now, and real uncertainty about exactly where it delivers the most
value. We pull together the current evidence for variable rate nitrogen application, covering the methodological, practical,
governance and cost angles, with an eye on where practice has genuinely settled and where farms and advisors are still largely
working it out for themselves. Selective, context-specific adoption looks better supported by the evidence gathered here than either
broad rollout or blanket avoidance.
