net.simplace.sim.components.models.lintul5.modular.NPKSupply

Lintul5 - Simple generic model for simulation of crop growth - NPKSupply part

This sim component calculates the NPK supply part from NPK sim component. It takes daily update rates iNUPTR, iPUPTR, iKUPTR and N limiting factor iNLIMIT as input. It outputs soil available NPK amounts.
