A review", "description": "Abstract

Nitrous oxide (N2O) is the contributor to agricultural greenhouse gas emissions with the highest warming global potential. It is widely recognised that traffic and animal-induced compaction can lead to an increased potential for N2O emissions by decreasing soil oxygen supply. The extent to which the spatial and temporal variability of N2O emissions can be explained by soil compaction is unclear. This review aims to comprehensively discuss soil compaction effects on N2O emissions, and to understand how compaction may promote N2O emission hotspots and hot moments. An impact factor of N2O emissions due to compaction was calculated for each selected study; compaction effects were evaluated separately for croplands, grasslands and forest lands. Topsoil compaction was found to increase N2O emissions by 1.3 to 42 times across sites and land uses. Large impact factors were especially reported for cropland and grassland soils when topsoil compaction\uffe2\uff80\uff94induced by field traffic and/or grazing\uffe2\uff80\uff94is combined with nitrogen input from fertiliser or urine. Little is known about the contribution of subsoil compaction to N2O emissions. Water-filled pore space is the most common water metric used to explain N2O emission variability, but gas diffusivity is a parameter with higher prediction potential. Microbial community composition may be less critical than the soil environment for N2O emissions, and there is a need for comprehensive studies on association between environmental drivers and soil compaction. Lack of knowledge about the interacting factors causing N2O accumulation in compacted soils, at different degrees of compactness and across different spatial scales, limits the identification of high-risk areas and development of efficient mitigation strategies. Soil compaction mitigation strategies that aim to loosen the soil and recover pore system functionality, in combination with other agricultural management practices to regulate N2O emission, should be evaluated for their effectiveness across different agro-climatic conditions and scales. 2017-2021 Automated chamber (Eosense eosAC) and Picarro G2508 GHG analyzer flux data for CO2, CH4, and N2O from corn, pasture, and alfalfa, and 2018-2021 continuous soil sensing data (oxygen, moisture, and temperature) from corn and alfalfa ## Description of the data and file structure Alfalfa _Chamber, Corn _chamber, and Pasture _chamber flux data tab: Alfalfa: Continuous soil flux measurements from January 2017-February 2021 Corn: Continuous soil flux measurements from July 2017-October 2021 Pasture: Continuous soil flux measurements from April 2019-July 2022 * Chamber * ChamberPressure (kPa) * ChamberTemperature (K) * CO2 flux: CO2 _umol/m2/s * CH4 flux: CH4 _nmol/m2/s * N2O flux: N2O _nmol/m2/s * Site Year Alfalfa, Corn, Soil Sensor Data tab: Measurements at 10, 30, and 50 cm soil depths from October 2018-February 2021 * Temp = Temperature in Celsius * VWC= volumetric water content in m3/m3 * O2 = Oxygen concentration in % * TIMESTAMP: Date and Time * Temp _10cm (C) * Temp _30cm (C) * Temp _50cm (C) * VWC _10cm (m3/m3) * VWC _30cm (m3/m3) * VWC _50cm (m3/m3) * O2 _10cm (%) * O2 _30cm (%) * O2 _50cm (%) NEE: Net Ecosystem Exchange (\u00b5molCO2 m-2 s-1) data can be found in Ameriflux datasets available at URLs below ## Sharing/Access information Links to other publicly accessible locations of the data: Was data derived from another source?
