Plant and crop Models

A Crop Model Example

    TOMSIM example

    The following diagram presents the TOMSIM crop simulator flow chart, developed by HPC at Wageningen University for a tomato crop (Heuvelink, 1996, 1999).

    In this model, the loop involves four main computational steps and the LAI is updated from the leaf biomass compartment pool at each growth cycle (see the prelimimary Eco-physiology course for details).

    TomSim PBM diagram
    TOMSIM tomato crop simulator workflow.
         Four organ compartments are defined, including the root system.
         At each growth cycle, the biomass allocated to leaves allows the LAI update for the next cycle.
