Start | Index | Overview • PREV | UP | NEXT The sim components in the package lintul5 implement the Lintul5 algorithms from (L5). They are designed to reproduce same results (up to rounding errors) as the original FST program.
The original model is subdivided into multiple sim components (which should be used in the following order to be as close as possible to the original algorithm).
Daylength calculation is performed by the transformer component AstronomicParametersTransformer
Lintul5 component calculates the biomass and NPK part
The component calculates biomass and NPK corresponding to the original model's CROPP() routine.
It takes inputs from the components Irradiation, RadiationUseEfficiency, Phenology, WaterBalance.
It's outputs are used by WaterBalance and PotentialEvapoTranspiration.
For documentation of the algorithms please consult the orginal documentation (L5)
Has additional inputs iDoSow and iDoHarvest. The main routine starts running when iDoSow is true and runs every day until iDoHarvest is true.
The output WithCrop is true between iDoSow (incl.) and iDoHarvest (excl.). It's an indicator, that the calculation has been performed on that day.
As some parameters are given as interpolation tables, there have been added additional scale factors to make these values changeable for calibrations:
