There are multiple ways that nitrogen (N) use efficiency (NUE) can be assessed, and NUE indicators documented in the scientific literature for measuring crop N uptake efficiency, utilization several other agronomic indicators. At present, however, there is no consensus as to how should calculated reported across different agricultural industries Australia, which makes it difficult communicate data stakeholders a consistent manner. This variation terminology definitions also perform long-term industry-specific assessments of NUE, inform management practices, therefore guide future research development. The work this article was undertaken address lack harmonization evident Australia. Metrics used measure both Australia internationally critically reviewed collated, define, describe interpret guidelines suite key applied assess cross-sector productivity, profitability environmental aspects fertilizer use, effective communication findings implications. following proposed: (1) Fertilizer (NUtE), (2) (NUPE), (3) Agronomic (AE), (4) Partial factor productivity (PFPN), (5) Marginal return on (MRF). calculation, interpretation cross-industry usefulness these presented discussed. Worked examples provided based derived from Australian Government's More Profit Nitrogen (MPfN) Program, enabled values determined. These were compare contrast between identify opportunities where could potentially improved by strategies. Further, an indicator framework adapted irrigated cotton sugarcane cropping systems generic developed EU Expert Panel. concept MPfN Program become available.

The North China Plain is an important irrigated agricultural area in China. However, the effects of irrigation management on carbon emission are not well documented this region. Due to uneven seasonal distribution rainfall, mainly concentrated winter wheat growing season Plain. In study, we estimated CO2 and soil CH4 uptake from fields with different methods scheduling treatments using static chamber-gas chromatography method April May 2017 2018. Treatments included three (surface drip, sprinkler, border) levels that initiated as soon moisture drained 50%, 60%, 70% field capacity for a 0–100 cm profile were tested. results showed both significantly influenced (p < 0.05) cumulative emission, grain yield, global warming potential (GWP), GWP Intensity (GWPI), GWPI per unit applied, water use efficiency (WUE). Compared 60% FC, 50% FC de-creased accumulated 26.8–30.3% 17.8–25.4%, reduced emissions 7.0–15.3% 12.6–19.4%, respectively. Conversely, 6.5–13.3% 12.5–19.4% lower yield 10.4–19.7% 8.5–16.6% compared 2018, sprinkler border irrigation, drip at increased 11.3–12.1% 1.9–5.5%, while 7.5–8.8% 10.1–12.1% Moreover, 5.2–7.5% 6.3–6.8%, WUE 0.9–5.4% 5.7–7.4%, lowered 8.0–9.8% 10.1–12.0% interaction impacted uptake, amount, 2018 only entire study. Overall, optimal choice terms higher WUE, mitigating
