The easiest way to run RothC for a site is assuming that the only information available are the percent clay content in the topsoil, the annual amount of litter inputs, and monthly averages of climatic variables. For this example, we have the following climate data We also have the following values for … See more Zimmermann et al. (2007) proposed a soil fractionation scheme to obtain the initial C fractions in a soil and run the RothC model. They proposed a … See more Recently, Weihermueller et al. (2013) proposed a set of functions (pedotransfer functions) to obtain the initial values of RothC pool sizes using data on total carbon … See more You might have noticed that in all cases the model converges to the same final pool sizes. This is because this model, and actually all first-order pool models, … See more Falloon, P., Smith, P., Coleman, K., and Marshall, S. (1998).
