Comprehensive increase in CO<sub>2</sub> release by drying–rewetting cycles among Japanese forests and pastureland soils and exploring predictors of increasing magnitude
Published 2025-01-01“…The present study was performed to evaluate overall trends in the effects of DWCs on <span class="inline-formula">CO<sub>2</sub></span> release and to explore environmental and soil predictors for variations in the effect size in 10 Japanese forests and pastureland soils variously affected by volcanic ash during their pedogenesis. Over an 84 d incubation period including three DWCs, <span class="inline-formula">CO<sub>2</sub></span> release was 1.3- to 3.7-fold greater than under continuous constant moisture conditions (<span class="inline-formula"><i>p</i><0.05</span>) with the same mean water content as in the DWC incubations. …”
