Modules
LUCIA modules
The soil water, organic matter and plant modules are built on concepts of established models, namely KINEROS (Woolhiser et al 1990) and SPAW (Saxton and Rawls 2006), CENTURY (Parton et al 1987) and the Crop Growth Monitoring System CGMS (Supit 2003), which is based on the World Food Studies (WOFOST) model.
Model coupling with LUCIA
The livestock simulator LIVSIM is now a built-in module of LUCIA. LUCIA-LIVSIM has also been soft-coupled to the multi-agent model MPMAS (see Table 1).
