Evaluation of the analytical optimum water content θop. Each symbol represents a comparison between the simulated and the analytical θop for a simulated homogenous soil core. The simulated θop was derived from the simulated heterotrophic respiration (HR)–moisture relationship obtained by the microscale model (see Methods section); the analytical θop was calculated using Eq. (11) in Methods section. The different symbols represent comparisons for different simulated soil cores with a wide range of depths H, 2.5 ≤ H ≤ 100 cm, porosity values ϕ, 0.2 ≤ ϕ ≤ 0.8, and SOC contents CSOC, 0.005 ≤ CSOC ≤ 0.2 g g−1. The base values were H = 20 cm, ϕ = 0.58, and CSOC = 0.02 g g−1 in the simulations
