Temperature and moisture are minor drivers of regional-scale soil organic carbon dynamics.
González-Domínguez B, Niklaus PA, Studer MS, Hagedorn F, Wacker L, Haghipour N, Zimmermann S, Walthert L, McIntyre C, Abiven S. González-Domínguez B, et al. Among authors: mcintyre c. Sci Rep. 2019 Apr 23;9(1):6422. doi: 10.1038/s41598-019-42629-5. Sci Rep. 2019. PMID: 31015496 Free PMC article.
We estimated two SOC turnover times, based on bulk soil (14)C measurements (τ(14C)) and on a 6-month laboratory soil incubation (τ(i)). In addition, upon incubation, we measured the (14)C signature of the CO(2) evolved and quantified the cumulated production of diss …
