Description
Simple dynamic model of soil carbon content, with a time step of one year. The equations that describe the dynamics of this system are adapted from the Henin-Dupuis model described in Jones et al. (2004). The soil carbon content is represented by a single state variable: the mass of carbon per unit land area in the top 20 cm of soil in a given year (Z, kg.ha-1). It is assumed that soil C is known in some year, taken as the initial year.
The yearly change in soil C is the difference between input from crop biomass and loss.
Usage
1
carbonsoil.update(Zy, R, b, Uy)
Arguments
Zy
: Soil carbon content for year
R
: the fraction of soil carbon content lost per year
b
: the fraction of yearly crop biomass production left in the soil
Uy
: the amount of C in crop biomass production in the given year
Value
Soil carbon content for year+1.
