Abstract

The nitrogen critical load to avoid eutrophication has been calculated for a 32 year old stand of Sitka spruce in N.Wales which has been intensively studied for 4 years. Default and measured values for the mass balance equation have been used to calculate a range of probable nitrogen critical load values which have then been compared to the range estimated from methods other than the mass balance approach.
