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

Global Change Biology, Journal Year: 2024, Volume and Issue: 30(2)

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.

Increase in soil organic carbon by agricultural intensification in northern China

Biogeosciences, Journal Year: 2015, Volume and Issue: 12(5), P. 1403 - 1413

Abstract. Agricultural intensification has contributed greatly to the sustained food supply of China's population 1.3 billion over 30-year period from 1982 2011. Intensification several and widely recognized negative environmental impacts including depletion water resources, pollution bodies, greenhouse gas emissions soil acidification. However, there have been few studies this on organic carbon (SOC) at regional level. The present study was conducted in Huantai County, a typical intensive farming region northern China, analyze temporal dynamics SOC influenced by climate practices. results indicate that 2011, content density 0–20 cm layer cropland increased 7.8 ± 1.6 11.0 2.3 g kg−1 (41%) 21.4 4.3 33.0 7.0 Mg ha−1 (54%), respectively. stock (0–20 cm) farmland for entire county 0.75 1.2 Tg (59%). Correlation analysis revealed incorporation crop residues significantly SOC, while an increase mean annual temperature decreased Therefore, agricultural productivity sequestration China. In near future, more appropriate technologies practices must be developed implemented maintenance or enhancement elsewhere which also reduce non-CO2 emissions, since benefit additional storage is estimated smaller than N2O N fertilizer additions.
