Opis:
In Poland, soil cover has been identified in detail in terms of spatial variability which resulted in soil records that comprise data on soil properties put in order according to the criteria of administrative and physiographic division. These data were not available in the numerical format till quite recently which meant that their application did not fully meet present requirements of agriculture, environment and landscape conservation, modification of functions, etc. The newly created numerical soil map at the scale of 1.500 000 corrects this difficulty. The main information content of the map at the scale of 1:500 000 covers complexes of soil usefulness and soil types and subtypes. Basic characteristics such as granulometric composition, origin of the parent rock and land use attributes, i.e.: forest, grassland, arable land, waters or barren land, are also included. Apart from the soil coverage, the map contains 13 topographic coverages.

Opis:
Specific, humid climate of mountain areas has a great influence on the properties of soils and vegetation, as well as on the mutual relations between these inseparable elements of ecosystems. Research on the interdependence between soils and natural vegetation was carried out on ' the mountain meadows of the Bieszczady National Park. In conditions of the cooler and more humid mountain climate the peculiar character of the soils lies in the presence of organic surface horizon of properties varying considerably from the properties of deeper mineral horizons. This horizon is of great importance in the protection of scarce elements. It prevents pollutants from reaching the ecosystem. It influences the soil water economy. It prevents erosion. This buffer element of the mountain soils requires special protection - in the Bieszczady Mountains the erosion of the mountain meadow soils is only noticeable where the covering vegetation and the organic surface soil horizon were destroyed, e.g. on tourist tracks. The plants of the Bieszczady mountain meadows, together with their direct product - the organic surface soil horizon, prevents the chemical erosion of the mountain meadows, reducing the leaching of many biogenous elements, e.g. calcium.

Opis:
The Macroregion of the Mazurian Lake District and the adjoining mesoregion of the Sępopol Plain were formed during Baltic glaciation and in the post-glacial period. The existing habitat differentiation, especially large variations in the soil cover, is divided into three distinct landscape zones. The northern areas of the district are typical heavy and very heavy soils, composed of tight clays and loams, represented by brown soils and black earths. They contribute to the ecosystem stability. Hydrogenic soils occupy only a small area. Agricultural production, when carried out correctly, should not threaten the habitat and should be in harmony with the area in question. The central, moraine area of the Mazurian Lake District, with unique natural qualities, is comprised of different soil forms and various soil covers. Brown and lessive soils are dominant among mineral soils. Deluvial soils are common, which is a warning sign on the danger of erosion. Contribution of hydrogenic soils is clearly seen. Protection of these soils, as well as re-naturalisation of the selected areas, is becoming vital. This area badly requires ecological farming. Light and very light soils, mainly rusty and podzo! soils, accompanied by large areas of sensitive for transformation hydrogenic, muck, and mucky soils occur in the southern part of the district, in the area of outwash plains. Outwash plains call for complex solutions to improve the quality of their mineral soils, as well as utilisation and protection of hydrogenic soils.

Bialowieza National Park
Opis:
Natural variability of pseudogley forest soils in the Białowieża National Park was characterised on the basis of five soil exposures. Two of them were located in a water-logged site, one in a mound one in a patch with dominance of deciduous trees, and one in a spruce biogrup. It was found that pseudogley soils of a natural moist deciduous forest show additional differentiation in the form of characteristic micromosaics. There is a pronounced impact of the species structure in a treestand, uprooted trees and hoofed mammals on the properties of the soil cover. Changes resulting from the above biotic factory were observed in all the analysed physical, physico-chemical and chemical soil parameters.
