net.simplace.sim.components.management.NitrogenSurplus

The purpose of this sim-component is to calculate the balance of applied and available major nitrogen fertilizer, e.g., organic N, ammonium, nitrate with the plant update resp. demand. This can be used to calculate possible nitrogen loss due to a fertilizer surplus.
