net.simplace.client.simulation.lap.SeedsToSprouts

Distributes biomass from the seed to roots and leaves at begin of growth

The module is initialized/reset on iDoStart.

Distribution starts, when iDevelopmentStage is greater than 0.

Daily SeedsToRootsBiomass is the cDailyFractionRoots of cSeedWeight, unless cTotalFractionRoots has been reached.

The input iRWRT is augmented by SeedsToRootsBiomass and output as RWRT.

Same holds for leaves.

Example

If cSeedWeight=2 g/m^2, cDailyFractionRoots=.04 and cTotalFractionRoots=.34, then each of the first eight days of crop development, 2*.04=0.08 g/m^2 go additionally to the roots. On day nine, the total fraction is reached, so only 2*.02=0.4 g/m^2 go additionally to the roots.
