This sim component calculates the NPK demand part from NPK sim component. It does not calculate any biomass related part, but takes biomass of crop organs iWRT, iWST, iWLVG ad iWSO as an input. Available NPK is taken from the inputs iNMINT, iKPMINT, iKMINT. It outputs stress factors as well as NPK daily uptake rates.
