Fig. 11From: Modelling the effect of different agricultural practices on stream nitrogen load in central GermanyComparison between baseline and two agricultural scenarios. The nitrate-N load was decreased when all areas of rape and maize are converted to winter wheat (a). The monthly nitrate-N load, however, was increased when winter wheat and maize areas are converted to rape. This increase mainly occurred during the summer season after the crop harvestingBack to article page
