In 1994, a large survey of soil chemistry was undertaken in the county of Värmland in central Sweden (Lundström et al., 1998). The southern part of the county was affected by soil acidification whereas there were no such indications in the northern part. To investigate the influence of soil chemistry on the trees at the specific sites, the survey was continued by an analysis of needle chemistry (Norway spruce) which was undertaken at 150 of the 180 sites, and of tree growth at 65 of the 180 sites. Growth was expressed as a ratio between expected growth, estimated with a national, empirical growth model, and the growth observed in the field. In statistical analyses, using rank correlation, PCA and PLS, there were only weak indications of an influence of soil chemistry on needle chemistry and on tree growth. A moderate correlation between nitrogen and sulphur in needles was found, which was interpreted as an effect of deposition and of processes in the tree canopy. No obvious regional pattern of the growth ratio was found, in contrast to the clear pattern of soil acidification. The statistical analysis could not with any certainty point out any of the soil chemistry variables as especially important for the tree growth ratio.
