摘要:Abstract(#br)The role of erosive processes caused by the spring thaw of snow in the formation of heterogeneity of the arable horizon of sod-podzolic soils is estimated. In addition to carrying erosive material out of the field limits, it is constantly redistributed within the bor...

摘要:... One place (excavation CCV) was the arable land for a long time and strong agrogenic erosion. Another (excavation CCVI) have no plough horizon, it was used as a road place but we can say about eroding processes too.

摘要:The paper includes the results of determination of Atterberg plasticity limits of arable (0-25 cm) and subarable (25-50 cm) horizons in 53 pseudogley profiles from the community of Ub. On the basis of performed laboratory investigations, it has been found that the pseudogley belo...

摘要:... sunken, sub-surface and sub-soil) archaeological features on arable land can frequently be discovered due to visually detectable changes in crop growth termed cropmarks. The aim of this paper was to demonstrate the range of features identified through cropmarks on aerial ...

摘要:... The initial strongly saline shallow (crusty) solonetz soils with a chloride-sulfate or sulfate-chloride composition of salts have transformed into slightly saline solonetzic and solonchakous agrozems with sodium sulfate salinity or with increased alkalinity in the middle of the soil profile and a dealkalized arable horizon...

摘要:... These maps allow an understanding of the geochemical nature of the rock assemblages, the mineral potential of the area, the ecological situation, soil fertility and chemical pollution level of the arable horizon, and recommendations on nature management. This approach is...

摘要:... Soil`s cultivation in the gardens leads to the formation of compacted horizon on the soil depth of 10-20-30 cm in which density of constitution is essentially increasing as compared with soils used for field`s cultures ( tf> t0,05).The most compaction was determined by tr...

摘要:... The result is defined by a number of new features (arable horizon, sub-arable horizon, layered and reversed profiles) and intensification of some processes like dehumification, compaction, de-structuring etc. Specified processes are distributed and have a common characteristi...
