MODELLBERÄKNING AV AVRINNING OCH KVÄVELÄCKAGE FRÅN TVÅ ÅKRAR I SYDSVERIGE / Modelling Runoff and Nitrogen Leaching from Arable Lands in Southern Swede
A conceptual model for simultaneous computation of runoff and inorganic nitrogen leaching has been developed and tested. The model is semiempirical with coefficients that are calibrated against observed data. The model has been verified against data from two small fields of arable land in southern Sweden. The results indicate that a major part of variations of concentrations of inorganic nitrogen in runoff water can be explained by this model approach.
