Abstract
Digitised maps of Quaternary deposits, 40K radiation and agricultural databases (IACS) were used to estimate the distribution and land use of agricultural organic soils in Sweden. The total area of agricultural land (cropland and pastures) in Sweden 2003 was estimated to be 3 496 665 ha and 8.7% of this area (301 487 ha) was classified as agricultural organic soil, with 202 383 ha of deep peat, 50 191 ha of shallow peat and 48 913 ha of gyttja. Using detailed information from the agricultural databases, it was possible to estimate the cultivation intensity of the agricultural land. One-third of the agricultural area of organic soils was intensively cultivated with annual crops and the remaining area was extensively used, dominated by managed grasslands and pastures. There was a great variation in cultivation intensity between areas, from 55% annual crops down to 9%. Peat soils were in general less intensively managed than gyttja soils.
