fW.RothC

Calculates the effects of moisture (precipitation and pan evaporation) on
decomposition rates according to the RothC model.

Functions for modeling Soil Organic Matter decomposition
in terrestrial ecosystems with linear and nonlinear systems of differential equations.
The package implements
models according to the compartmental system representation described in
Sierra and others (2012) <doi:10.5194/gmd-5-1045-2012> and Sierra and others (2014)
<doi:10.5194/gmd-7-1919-2014>.
