“…A CO 2 efflux (and effluxes of other greenhouse gasses) from the soil surface is influenced by many abiotic and biotic factors including soil temperature, soil water content, organic carbon content, composition and activity of microbial community, etc. (e.g., Balashov et al, 2021;Balogh et al, 2011;Carmo et al, 2014;Davidson et al, 1998;Fér et al, 2014Fér et al, , 2018Horák et al, 2020;Hussain et al, 2022;Li et al, 2022;Qayyum et al, 2017;Raich and Schlesinger, 1992;Schaufler et al, 2010;Seki et al, 2022). The microbial activity and consequently the CO 2 emission can be influenced by many soil amendments used to increase soil fertility.…”

The goal of this study was to evaluate the effect of products from a municipal wastewater treatment plant on the H2O and CO2 effluxes from two soils. The net H2O and CO2 effluxes were measured at the surface of nine beds with two different soils (Cambisol and Arenosol) and two crops (maize or vegetables). Soils in some beds were amended with stabilized sewage sludge (bed with Cambisol and maize) or composted sewage sludge (two beds with Cambisol and both crops) or were irrigated with treated wastewater (two beds with Cambisol and both crops, and one bed with Arenosol and vegetable). Remaining beds were irrigated with tap water (two beds with Cambisol and both crops, and one bed with Arenosol and vegetable). While stabilized and composted sewage sludge positively affected the CO2 emission, the effect of treated wastewater was not confirmed. Different treatments had negligible effect on the water efflux, which was mainly affected by the plant canopy that influence the temperature of the soil surface. Statistical analyses showed that trends of the CO2 efflux with respect to various scenarios measured on different days changed during the season. No significant correlations were found between the average H2O and CO2 effluxes and measured soil properties.
