A global meta‐analysis of yield‐scaled N₂O emissions and its mitigation efforts for maize, wheat, and rice

Abstract Maintaining or even increasing crop yields while reducing nitrous oxide (N 2 O) emissions is necessary to reconcile food security and climate change, the metric of yield‐scaled N O emission (i.e., per unit yield) at present poorly understood. Here we conducted a global meta‐analysis with more than 6000 observations explore variation patterns controlling factors for maize, wheat rice associated potential mitigation options. Our results showed that average across all available data followed order (322 g Mg −1 , 95% confidence interval [CI]: 301–346) > maize (211 CI: 198–225) (153 144–163). Yield‐scaled individual crops were generally higher in tropical subtropical zones temperate zones, also trend towards lower intensities from low high latitudes. This was better explained by climatic edaphic fertilizer management, their combined effect predicted 70% variance. Furthermore, our analysis significant decrease use efficiency production systems cereal >10 ha (maize), 6.6 (wheat) 6.8 (rice), respectively. highlights indicators can be used as valuable proxies reconciling trade‐offs between mitigation. For three major staple crops, fertilization up 30%, optimizing timing placement application using enhanced‐efficiency fertilizers significantly reduced similar yields. data‐driven assessment provides some key guidance developing effective targeted adaptation strategies sustainable intensification production.

Sampling frequency affects estimates of annual nitrous oxide fluxes

Scientific Reports, Journal Year: 2015, Volume and Issue: 5(1)

Published: Nov. 2, 2015

Abstract Quantifying nitrous oxide (N 2 O) fluxes, a potent greenhouse gas, from soils is necessary to improve our knowledge of terrestrial N O losses. Developing universal sampling frequencies for calculating annual fluxes difficult, as are renowned their high temporal variability. We demonstrate daily was largely required achieve within 10% the ‘best’ estimate 28 datasets collected three continents—Australia, Europe and Asia. Decreasing regularity measurements either under- or overestimated with maximum overestimation 935%. Measurement frequency lowered using strategy based on environmental factors known affect variability, but still more than once week. Consequently, uncertainty in current global budgets associated upscaling field-based can be decreased significantly adequate frequencies.
