Evaluation of discrepancies in spatial distribution of rainfall erosivity in the Czech Republic caused by different approaches using GIS and geostatistical tools
covariate geostatistics R factor rainfall intensity rainfall total USLE/RUSLE-GIS method
2017/6/26
The study presents all approaches of rainfall erosivity factor (R) computation and estimation used in the Czech Republic (CR). A lot of distortions stem from the difference in erosive rainfall criteri...

Extensive soil sampling and screening assessment of ecosystem risks combined with a multidimensional statistical analysis were used to estimate and spatially characterize the ecosystem risks stemming ...
Land use analysis in terms of farmland protection in the Czech Republic
agricultural land management agricultural land protection land take
2016/2/22
The agricultural land acreage in Central Europe, including the Czech Republic, rapidly decreases. This study presents the trends of agricultural land acreage reduction in the period 1966?013, with res...
Eff ects of aff orestation on soil structure formation in two climatic regions of the Czech Republic
water-stable aggregates (WSA) mean weighted diameter
2015/5/18
The aim of this study was to determine the effect of agricultural land afforestation on soil characteristics.
Two sites in two regions of the Czech Republic were evaluated, at lower as well as highe...
Fluctuations in the properties of forest soils in the Central European highlands (Czech Republic)
acidification cyclometric functions forest ecosystem soil chemistry time-series
2015/3/10
Fluctuations in forest soil properties were described using a time series analysis of the clay content, the chemical (CaO, MgO, Corg, and Ntot) and physicochemical (pH and base saturation (BS)) soil p...
Relating extent of colluvial soils to topographic derivatives and soil variables in a Luvisol sub-catchment, Central Bohemia, Czech Republic
digital elevation model digital soil mapping loess soil erosion soil organic carbon
2015/3/10
Colluvial soils, resulting from accelerated soil erosion, represent a significant part of the soil cover pattern in agricultural landscapes. Their specific terrain position makes it possible to map th...
Thermal properties of representative soils of the Czech Republic
heat capacity laboratory measurements sensor comparison soil thermal properties soil-water content soil types thermal conductivity
2015/3/9
Knowledge of soil thermal properties is essential when assessing heat transport in soils. Thermal regime of soils is associated with many other soil processes (water evaporation and diffusion, plant t...
HYPRESCZ - database of soil hydrophysical properties in the Czech Republic
HYPRES pedotransfer functions soil water retention curve
2015/3/9
The database of soil hydrophysical properties in the Czech Republic called HYPRESCZ was created. It is based on the European database HYPRES, HYdraulic PRoperties of European Soils, and follows its st...
Soil toposequence under man-planted vegetation in the Krkonoše Mts., Czech Republic
