Agriculture is a major contributor to greenhouse gas (GHG) emissions and one of the sectors most vulnerable climate change. Mulching, application an organic layer agricultural field, promising practice, with aim reducing evaporation, preventing soil erosion stabilising yields. While mulching has become popular research topic in recent years, little known about its effects on change adaptation GHG emissions. We conducted weekly measurements nitrous oxide (N2O) analyzed related parameters, including nitrate content, temperature, moisture, cabbage field fertilization as treatments. Fertilization increased N2O emissions, but rye mulch had no significant effect Soil microclimatic parameters changed substantially under mulch, significantly higher moisture lower, less fluctuating temperatures. At same time, yields combined. In conclusion, our findings suggest that can aid via buffering, while not increasing without compromising yield, owing high C/N ratio mulch.

Abstract Crop rotations are considered a promising strategy for mitigating greenhouse gas (GHG) emissions and enhancing soil organic matter in agricultural land. However, studies often focused solely on either GHG or carbon (SOC) changes, rather than integrating both indicators. We conducted 4‐year (2018–2021) crop rotation study to examine effects of six systems three ecoregions (sub‐humid, sub‐semiarid, semiarid) emissions, SOC C footprints Saskatchewan, Canada.

Satellite observations from instruments such as the TROPOspheric Monitoring Instrument (TROPOMI) show significant potential for monitoring spatiotemporal variability of NO2, however they typically provide vertically integrated measurements over tropospheric column.

Draining peatlands for forestry in the northern hemisphere turns their soils from carbon sinks to substantial sources of greenhouse gases (GHGs). To reverse this trend, rewetting has been proposed as a climate change mitigation strategy. We performed literature review assess empirical evidence supporting hypothesis that drained forested can turn them back into sinks. also used causal loop diagrams (CLDs) synthesize current knowledge how water table management affects GHG emissions organic soils. found an increasing number studies last decade comparing rewetted, previously peatlands, with or pristine peatlands. However, comparative field usually report relatively short time series following experiments (e.g., 3 years measurements and around 10 after rewetting).
