net.simplace.sim.components.crop.translocation.BiomassTranslocation

BiomassTranslocation calculates daily biomass translocation after anthesis.

Certain amount (e.g. 20%) of produced biomass before anthesis is relocated to grains after anthesis.

All equations documented in Slotani and Sinclair, 2012 pp. 133-135.

\[TDM = (WST_{DayOfAnthesis}+WLV_{DayOfAnthesis}+WRT_{DayOfAnthesis}) \cdot FRTDM \] \[TRANSL_{Day} = TDM \cdot (DevStage_{Day} - DevStage_{Day - 1})\]

The biomass to translocate is subtracted from the biomass of dead leaves and added to the biomass of storage organs. If there is not enough dead leaves biomass, then biomass is translocated from stems.
