Short-term impacts of different tillage practices and plant residue retention on soil physical properties and greenhouse gas emissions

Reducing tillage intensity and plant residue retention have the potential to mitigate climate change by reducing soil greenhouse gas emissions. Few comparative studies explored effects of different practices on net balance GHG emissions in short term (1–2 years). We hypothesised that decreases compared conventional ploughing removal. estimated practices; no-tillage, minimum-tillage traditional as well on; 1) bare-soil emissions, 2) ecosystem exchange (NEE), ultimately, 3) for mitigation, CO2 equivalent. fluxes were measured using static chamber method physical properties assessed X-ray Computed Tomography (CT) a range methods. No-tillage increased bulk density shear strength ploughed soil. Soil moisture content organic matter at 0−5 cm depth higher no-tillage soil−CO2 CH4 uptake but reduced NEE−CO2 NEE−CH4 uptake. No resulted 56 % 40 reduction equivalent respectively combined crop-soil measurements. Changes interlinked changes pore architecture properties. Taken together our data demonstrate contribute mitigation through
