- Abstract
A combination of land cover data and WRB diagnostic traits was used to form four soil groups based on the extent of anthropogenic influence: 1. areas with no soil, 2. areas with anthropogenic soils, 3. natural soils with evidence of human transformation, 4. soils in a natural condition. All the land cover classes could be unequivocally assigned to one of these groups. This method was then applied to evaluate the naturalness of the soil cover in Hungary. No soils meeting the definition of soil according to FAO guidelines were found on 2% of the land surface, anthropogenic soils (Anthrosol or Technosol) were characteristic of 6%, natural soils on which the level of anthropogenic activity reached the WRB diagnostic limit values made up 66% of the land surface, and only 26% of the soils were in a natural or near-natural condition. In terms of diagnostic soil types, the chernozem, meadow and alluvial soils exhibited the greatest extent of anthropogenic influence, while most of the soils in a natural condition were skeletal and lithomorphic soils. There were also considerable territorial differences: the highest rate of anthropogenic transformation was found in the Hajdúság and Körös- Maros Köze regions, while the highest proportion of natural soils was recorded on hilly areas in the Northern Mountains. The method developed for evaluating the naturalness of the soil can only be used as a rough estimate, but it nevertheless gives a good idea of the extent to which Hungarian soils have been exposed to anthropogenic effects, and of the importance of human activity, which is considered to be the sixth soil-forming factor, but which has been less well studied than the other five factors.
