Remote sensing data have an important advantage; the data provide spatially exhaustive sampling of the area of interest instead of having samples of tiny fractions. Vegetation cover is, however, one of the application constraints in soil science. Areas of bare soil can be mapped. These spatially dense data require proper techniques to map identified patterns. The objective of this study was mapping of spatial patterns of bare soil colour brightness in a Landsat 7 satellite image in the study area of Central Bohemia using object-oriented fuzzy analysis. A soil map (1:200 000) was used to associate soil types with the soil brightness in the image. Several...

This paper focuses on numerical modelling of soil water movement in response to the root water uptake that is driven by transpiration. The flow of water in a lysimeter, installed at a grass covered hillslope site in a small headwater catchment, is analysed by means of numerical simulation. The lysimeter system provides a well defined control volume with boundary fluxes measured and soil water pressure continuously monitored. The evapotranspiration intensity is estimated by the Penman-Monteith method and compared with the measured lysimeter soil water loss and the simulated root water uptake. Variably saturated flow of water in the lysimeter is simulated...

Anthropogenic soils are formed by human activities. The contents of potentially risk elements are one of the most important criteria of the exploitability of such soils for the agricultural production. The aim of this paper is to assess the contents of the selected potentially risk elements in 16 areas of the Sokolov region, including 5 reclaimed areas and 11 natural soils. 116 sampling locations were analysed in total. Another aim is to analyse the relationships between the elements, using multivariate statistical methods. The contents of the risk elements studied were in most cases under the limit values. In some cases, as with Pb, they were very...

In the Czech Republic, industrial areas, mining areas and military zones can be found. These areas represent potential risks for the agricultural production from the viewpoint of hygienic standards. The industrial areas and mining areas are the topic of the present study. The industrial areas are combined with present or past mining activities in the Czech Republic in most cases. The widest industrial areas located in North-Bohemian and North-Moravian regions were based on the mining of brown and black coal. North-Bohemian region was affected by the combustion of brown coal in the power stations during many years and the region was a part of the Middle-European...
