Earthworms are known to stimulate soil greenhouse gas (GHG) emissions, but the majority of previous studies have used simplified model systems or lacked continuous high-frequency measurements. To address this, we conducted a 2-year study using large lysimeters (5 m2 area and 1.5 m depth) in an ecotron facility, continuously measuring ecosystem-level CO2, N2O, H2O fluxes. We investigated impact endogeic anecic earthworms on GHG emissions ecosystem water use efficiency (WUE) simulated agricultural setting. Although observed transient stimulations carbon fluxes presence earthworms, cumulative over indicated no significant increase CO2 emissions. Endogeic reduced N2O during wheat culture (- 44.6%), this effect was not sustained throughout experiment. No consistent effects evapotranspiration WUE were found. Our suggests that do significantly contribute two-year period experimental conditions mimic These findings highlight need for realistic experiments

Abstract Earthworms are known to stimulate soil greenhouse gas (GHG) emissions, but previous studies have used simplified models or had limited measurements. To address this, we conducted a two-year study using large lysimeters in an ecotron facility, continuously measuring ecosystem-level CO 2 , N O, and H O fluxes. We investigated the impact of endogeic anecic earthworms on GHG emissions ecosystem water use efficiency (WUE) agricultural setting.
