Abstract
Poland is considered as a country with very well mapped soil cover and detailed soil cartographic materials. Despite this, in some areas there are “white spots” on soil-agricultural or soil-habitat maps. Such situation includes the Wielka Żuława Island in Jeziorak Lake (Iława Plain). This island is an inaccessible and almost abandoned – detailed field research is therefore very difficult. The aim of the work was to check the possibility of using existing cartographic materials and remote sensing data to develop a genetic map of the soils of this area. In order to interpret the existing materials, preliminary field works was carried out: 6 soil pits and 22 manual drillings to the average depth of 2 m. These studies showed significant diversity of soil cover. The largest share within central, upland part of island have autogenous rusty and clay-illuvial soils. The lower locations – mainly along the coast of the island – were dominated by organic soil. The relief model enables precise determination of the boundary between mentioned autogenous and hydrogenic soils. In the group of organic soils, a large area was degraded which was expressed by occurrence of murshic soils. The DEM obtained from LiDAR data, shows networks of (almost invisible in aerial photos) drainage ditches and channels, which turned out to be very useful in determining the extent of the mentioned degraded soils. The greatest difficulties concerned the extent of soil formed as a result of human influence – colluvial and anthropogenic soils. In the first case, a relief model combined with archival orthophotomaps allowed for an approximate estimation of the places where these soils occur. Both elements (DEM and archival aerial photos) were also used to estimate the extent of occurrence of technogenic soils.
