Abstract

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

Abstract

Skage Gård is a typical West coast farm. Its total area is 30 ha, with 23 ha of forest and 7 ha of fields (including 60 ha with christmas trees and 0,5 ha of greenery). The production of christmas trees started 35 years ago. Christmas tree sales make up 60-65 % of the farms income, and this percentage is expected to increase. Between 3,000 and 5,000 trees are planted each year and there are approximately 55,000 trees now in production. Most of these must be formed and trimmed
