Carbon decomposition data from oxygen-limited soils

To understand carbon (C) decomposition under cyclic, time-varying
oxygen (O 2 ) fluctuations, we incubated two
disparate soils (Oxisol and Mollisol) under five fluctuating oxygen
treatments (0, 2, 4, 8, or 12 days of anoxic conditions followed by
4 days of oxic conditions), and measured C decomposition as
CO 2 and CH 4 (and their
stable isotope compostion) at 2–4-day measurement timesteps for 384
days. We also used a process-based mechanistic model to test C
decomposition in response to O 2 fluctuations.
This dataset supports the findings described in the associated
manuscript by Huang et al. (2021).
