The article presents an overview and brief characteristics of the selected soil information systems in the Czech Republic. It suggests synchronisation of their development, particularly some convergence of the Land Evaluation Information System and Soil and Terrain Digital Database. In the pilot area of Litoměřice district, it demonstrates the application of the SOTER methodology for the construction of middle- and detail-scale soil maps, using the data from the General survey of agricultural soils. It not only shows the variety of the district soil conditions, but it also supplements them with the data gathered in the 2006 soil survey.

For the research of irrigation optimization and nitrate leaching it is important to know the short-term soil moisture variation during percolation episodes as well as its seasonal pattern. Dielectric soil moisture sensors Virrib (AMET - Consortium) and ThetaProbe ML2x (Delta-T) were used for this purpose over several years for measuring soil moisture content at hourly intervals in Valečov (49°38'40" N, 14°30'25" E, 461 m a.s.l.), Czech Republic, in a deep loamy Stagnosol soil underlain by weathered paragneiss. One-point field calibration was made each spring at the time of sensor installation over three (for Virribs) or two (for ThetaProbes) consecutive...

Erosion, which is one of the most important exogenous processes forming the landscape, has become a main degradation factor affecting agroecosystems. One of the direct erosion effects is a change in the soil cover structure. Colluvisols, originating in the material accumulated in depressions and foot part of slopes, represent a significant element in such a segmented soil mosaic. In the Chernozem loess area of Žďánický les, a method of areal delimitation of Colluvisols was proposed. Considering the homogeneity of the relative soil properties, the terrain morfometric characteristics (slope, profile curvature, and plan curvature) were applied as the...

Soil temperatures were analysed for the climatological station Pohořelice during the period of 1961-2000. According to the agroclimatic zoning, this region is a part of warm macroarea, mainly warm area, mainly dry subarea, and a district of mainly cold winter. The average annual air temperature is 9°C and the average year precipitation total is 475 mm. For the characterisation of the soil temperature were used the average monthly soil temperature determined from daily averages, maximal monthly soil temperature determined on the basis of daily maximums, and minimal monthly value determined on the basis of daily minimums. In the Czech Hydrometeorological...

The knowledge of sorption-desorption processes of polycyclic aromatic hydrocarbons (PAHs) in natural solids is essential to predict the fate, transport, and environmental risks of these pollutants. In this study, the effect was investigated of temperature on the sorption-desorption of three PAHs (naphthalene, phenanthrene, and pyrene) in two natural solids with different organic carbon contents. In all cases, the sorption isotherms obtained could be well described by the linear sorption model. The analysis based on the measured isotherms and the corresponding equilibrium partition coefficients (Kp) revealed that (1) the sorption of PAHs increased...
