THE SOLLING NORWAY SPRUCE SITE

The Selling Fl site is a typical Norway Spruce (Picea abies) plantation forest on acid soil, with a well-developed mor humus layer, low soil biological activity and sparse ground vegetation. Inputs, outputs and internal transfers of chemical constituents have been measured continuously for more than twenty years, and were complemented by plant physiological, hydrological, micrometeorological and soil biological measuring programmes in that time. A comprehensive dataset was compiled from many sources to apply a variety of models to the Selling spruce site dataset in the framework of the workshop ''Comparison of Forest-Soil-Atmosphere Models'' at Leusden in the Netherlands. This paper gives background information on the site, such as land use history, climate, soil and deposition regime, and on the dataset (important trends and limits of accuracy).
