The results reported deal with plant biomass, primary production and mineral cycling. Earlier the two first
properties have been reported, but the mineral cycling not. As the results still are valid and can serve as refer-ence material, it is considered essential to have them published. The cycling of carbon, nitrogen and sulfur are
elements, which are affected by a changing climate and deposition. Repeated investigations make it possible to
address questions like the forest as a source or sink for carbon
