From: Modelling the effect of different agricultural practices on stream nitrogen load in central Germany
Monthly nitrate-N loads for the baseline and two agriculture management scenarios for the period 2006–2009. The results showed that the nitrate-N load enriches when the fertiliser application is increased by 20 % for all crops (a). While, when only organic farming is used, the NO3-N load reduces significantly compared to the baseline predictions
