net.simplace.usermodules.heidi.modules.lintul5slimagmip.Lintul5SlimNSlimNitrogenLegacy

Calculates the amount of Nitrate and Ammonium in the soil per layer. Routines taken from SLIM. Leaching of solutes slightly different than in SLIM, because water movement between layers is performed at once and not in aliquotes.
