turnoverFit

This function finds two possible values of turnover time from 
radiocarbon sample assuming a one pool model with carbon at equilibrium.

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>.
