Extreme Rainfall Amplified the Stimulatory Effects of Soil Carbon Availability on N<sub>2</sub>O Emissions Open
Ongoing climate change is predicted to increase the frequency and intensity of extreme rainfall, which will dramatically alter soil nitrous oxide (N 2 O) emissions, especially changes in soil organic carbon (SOC) due to anthropogenic manag…

Nitrification inhibitors reduce N2O emissions from Mollisols by potentially targeting Nitrosospira cluster 3a and denitrifiers Open
Nitrification inhibitors (NIs) are widely used to mitigate nitrous oxide (N2O) emissions from agricultural soils. However, its efficiency is highly uncertain owing to varying environmental conditions and still-debated inhibition mechanisms…

Crop residue harvest: a growing opportunity for greenhouse gas emissions abatement Open
Near-term commitments to net-zero greenhouse gas emissions (GHG) require the agriculture sector to reduce emissions and sequester CO2. Harvesting of crop residues can contribute to these goals; however, uncertainties about the effects on g…
