A new process-oriented model, MERLIN has been tested on a nitrogen-manipulated catchment at Gårdsjön, Sweden to elucidate the time aspects of nitrogen `saturation`. The model is calibrated to the period 1930.90 and the first 4 years of N addition (1991-94), and then compared with data for the 5th and 6th years. The model indicates that most of the added N goes to forest floor soil and very little to plants. The model correctly predicted the flux of N out of the cathment the 5th year, but overestimated the 6th year. A sensitivity analysis is needed, along with further testing on a variety of ecosystems to evaluate the utility of the model
