Opis:
Anthropogenic alterations of the recent millennia of our era, in the loess areas of the Lublin Upland are clearly visible in the composition and character of the sediments that fill river valleys. This paper is an attempt to review this issue on the example of a small river valley that runs through the loess relief regions near Lublin. Samples were taken from deep drilling (up to 6 m) in the three cross-sections of the valley (Ożarów, Jastków, Snopków). A total of 172 samples taken from 5 drillings were investigated. The results obtained allow to conclude that delluvial processes dominated in the course of sediment formation that filled the Ciemięga river valley. Those delluvial processes started in the Neolyth by climatic changes and cutting down forests for the incoming agriculture - and have been intensified since the Middle Ages up till now. It is seen in a clear correlation between the growing part of ash components and mineral interbeddings in the peat deposits, as well as in the presence of cereal grains and weed pollen from cultivated fields in the investigated samples. In the chemical composition of the sediments, anthropogenic enrichment of K, P, Fe, Mn, Pb, Cr, Cu, Zn, and Co is observed.

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:
In order to estimate sorption properties of gypsic rendzinas from the Niecka Nidziańska area as well as compare a composition of exchangeable cations in arable and turf soils 24 profiles have been investigated which represented following subtypes: initial, proper, chernozemic and brown ones, and derived from 3 types of miocene gypsum: selenite, shaly and compact gypsum. On the basis of the investigations it has been found that sorption properties of gypsic rendzinas were formed under influence of lithological factor and depend on the activity of the parent rock which is expressed by a content of the active calcium in the rock. Humous horizons of the arable soils characterised of a slightly lower complex exchange capacity and a higher contribution of potassium and magnesium in the composition of exchangeable ions in comparison with analogous horizons of the turf soils. A content of exchangeable cations permitted to count investigated soils among the soils with saturated complex of exchangeable cations. In their complex dominated calcium and the contribution of acid cations was small.

Opis:
Investigations have been carried out on the soil material taken from 46 profiles representing lithogenic soils from non-forest areas of the Tatra National Park. When selecting soil material an altitude above sea level (over 1250 m a.s.l.), a rock parent type (non-calcareous and calcareous) were taken into account, in case of non calcerous soils, the weakly developed soils - rankers were selected. On the basis of the investigetions the following conclusions have been drawn: sorption properties of ectohumus horizons in most of investigated lithogenic soils (rankers and rendzinas) are differ- enciated and formed under the influence of parent rocks. Ectohumus of Oh horizons of rankers sorbed exchangeable cations in following order H+>Ca2+≥Mg2+>K+>Na+. In composition of cations in Oh horizons of rendzinas dominated cations of calcium and the order was as follows: Ca2+>Mg2+>H+>K+≥Na+. In ectohumus of Oh horizons of rendzinas occurring under bilberry heath and pine dwarf and rankers the composition of exchangeable ions as well as a degree of base saturation were close. In investigated soils sorption properties of mineral or organic-mineral horizons AC or ABC, occurring in direct contact with the parent rock, were formed under the influence of lithogenic factor.

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.
