As a pioneer species of R life strategy Salix acutifolia is an early coloniser, promoting the formation of soil in sandy areas. Initially, the area around the base of S. acutifolia is colonised by cryptogams. Then, soil formation takes place as S. acutifolia grows and the canopy develops. As a broadleaved species, S. acutifolia produces a lot of biomass. Good habitat conditions are created for the development of microorganisms accelerating the process of leaf decomposition and humus formation. This encourages the subsequent entry and growth of vascular herbs under the canopy of S. acutifolia, which hasten the process of soil and plant succession. After 5 years, a large number of Pinus sylvestris seedlings develop under the S. acutifolia canopy. P. sylvestris outcompetes S. acutifolia for nutrients and eventually eliminates S. acutifolia from the site by contributing to soil acidification. P. sylvestris then becomes the dominant influence on the physico-chemical properties of the soil.

The content of phosphorus, aluminium, and iron compounds soluble in an HCl solution and in ammonium oxalate varies widely in different horizons of the investigated gley-podzol soils. Phosphorus compounds accumulate in the surface organic and humus horizons, but they are also found in large quantities in the alluvial and gley horizons. The content of phosphorus compounds soluble in an HCl extract and in ammonium oxalate is related to the content of pedogenic aluminium and iron oxides. The phosphate retention varies significantly in soils studied and is determined by the content of amorphous aluminium and iron oxides. Peat and alluvial horizons have the highes tphosphate retention capacity among investigated soil formations.

The aim of the present research work was to evaluate the influence of lithogenic conditions on the physico-chemical properties, quantity and quality of humus components in the black earths from the Małopolska Upland. Soil samples were collected from 5 soil profiles which represented proper black earth (profiles No. 1-4) and degraded black earth (profile No. 5). All the investigated soils were under sward. The examined black earths were characterised by different physico-chemical properties strongly related to the parent rock type. Their pH level and sorption capability were decreasing with a decrease in the clay content of the soil texture. Humus resources were the lowest in sandy black earths (average 212 t ha-1) and the highest in the black earh derived from clay (454 t ha1). In the humus composition of the examined black earths, humic acids dominated over fulvic acids. In the A horizons, the Ch:Cf ratio was close to 1, and lower in the upper parts of these horizons which is typical of turf soils. Humus horizons in some of the investigated black earths were classified as epipedon anthropoid according to phosphorus content soluble in 1% citric acid (109 P kg-1 soil).

The presented studies show the important role of slope covers, which often differ in their properties from the underlying bedrock, and in the formation of the studied soil profiles and the occurrence of discontinuities within the parent soil material. The observed regularities affect the analysed physical properties, particularly as regards the amount of retention and filtration in the genetic horizons developed within the slope deposits zone (slope cover) and in the zone of rock weatheredin situ(residuum). The diverse properties of the two zones determine both moisture and water movement in a soil profile as well as within the soil cover of the whole slope.

Quite large areas of the alluvial soils in the valley of the river Bobr were destructed by the sand and gravel exploitation. After the recultivation measures, which consisted of backfilling of the open-castwith waste aggregate, levelling the surface and putting on such prepared surface 50-200 cm of the stripping material,the yield was very low.The field and laboratory experiments have shown that during the technical operations the soil was compacted to such degree, that the root growth and water permeability was restricted to large extent.The soil compaction was noted in the whole soil profile.The evidences of this process were the high bulk density( often over 1,8 Mg m-3), very low water permeability values and low air capacity. The situation during the 12 years from the finishing of the recultivation has not changed.

Weathering – soil forming processes were studied on the spoil heaps of an abandoned pyrite mine in Wieściszowice (German: Rohnau, Lower Silesia, Poland). These heaps of waste material were formed during the 19th century, with the mining ceasing in 1902. The material was not homogenous texturally (loam and sandy loam layers) and did not show coloured genetic horizons. In the soil formations, the humus horizon was approximately 10 cm deep, and contained approximately 10% of organic matter in various stages of decomposition. The reaction in the whole soil profiles was acidic (pH approx. 4.0), and composition quartz, feldspars, chlorites and micas prevail in the mineral. Pyrite was not observed among the minerals, although secondary sulphate minerals were found such as: gypsum, jarosite, fibroferrite and iron oxides (mainly goethite). Clay minerals included chlorite, illitic material (K-mica and Na-mica), kaolinite and smectite as well as mixed-layered minerals of the mica/smectite type.

Mud soils have developed in small depressions on the river floodplains of north-eastern Poland, these mud deposits being shallow, up to 50 cm, and have a 37-53% organic matter content. After drainage, they undergo a muck-forming process, the soil formations of dewatered sites not being abundant in nutrients or base compounds due to leaching connected to the muck-forming process. Higher amounts of Pb and Cd were reported in the surface layers of dewatered soils as a result of bioaccumulation and anthropogenic input.

Scientific data on the evolution of meliorated peat soils under the impact of agricultural use are presented. The following 3 soil groups are formed as a result of destruction of a peat layer after drainage of mires:peat soils containing more than 30% of organic matter, organic-mineral and mineral residual-peatysoils containing15-30% and less than 15% of organic matter,respectively.The classification of each of this group based on the criteria of the morphology of soil profile, ratio between organic and mineral parts of the soil and granulometric composition of mineral bedrock is given. Suggestions about nomenclature of new soils are presented.
