Abstract
Abstract The yearly and seasonal variations in water-soluble and phosphate-extractable SO2- 4 in the soil at two locations in Norway were measured during the years 1979–1981. Two small plots at each location were sampled. The variation in the SO2- 4 fractions between the plots was explained by the differences in soil properties. The correlation coefficients between water-soluble SO2- 4 and total S were not high, but significant. Both depletion and accumulation of soluble SO2- 4 during the period of investigation were measured. Amounts of precipitation could only partly explain the observed changes. No differences between the locations could be attributed directly to the higher input of anthropogenic sulphur to one of the locations.
