Abstract [en]

A forest soil survey was performed at 180 sites in the county of Varmland in mid-western Sweden. The survey included field observations, the total composition of the soil, the composition of the exchangeable pool and the soil solution at four depths. The southwestern part of Varmland was affected by soil acidification while no indications of soil acidification were found in the north. Evaluation of the data with principal component analysis (PCA) showed that the dominating variables, giving the same spatial distribution as the atmospheric deposition, were those of the soil solution composition and especially the concentration of total Al, inorganic Al and pH in the B-horizon. The composition of the exchangeable pool was less indicative of acidification. Sampling of soil solution in large surveys is possible by the centrifuge drainage technique.
