Opis:
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.

Opis:
The alluvial soils in the Bóbr river valley, devastated by sand and gravel exploitation, were reclaimed for agricultural use. After reclamation treatment, the newly formed soil was very acid. Application of 5 Mg/ha lime elevated soil pH to 6-7, but during the following years, soil pH dropped again by about one half of the pH unit a year. Rapid drop in the pH level can result both from geological and soil-forming processes. Efficiency of mineral fertilizers applied in various combinations did not give the expected results and the yield of cultivated plants was not satisfactory. Mineral fertilization in various combinations did not result in the expected yield levels.
