This study presents soil-moisture calibrations using low-frequency (15–40 MHz) time domain reflectometry (TDR) probe, referred to as water content reflectometer (WCR), for measuring the volumetric wat...
Impact of animal manure addition on the weathering of agricultural lime in acidic soils: The agent of carbonate weathering
Carbonate weathering Soil/atmospheric CO2 CO2 source/sink
2018/3/23
Fertilization and aglime (agricultural lime) application, as important agricultural activities in acid soil, exert an influence on the fluxes of carbon both between and within ecosystems. Animal manur...
Using HYDRUS to simulate the dynamic changes of Ca2+ and Na+ in sodic soils reclaimed by gypsum
cation exchange ion transport leaching
2016/2/22
Sodic soils are characterized by the occurrence of excess sodium to levels that can adversely affect soil structure. In recent years, with the advent of alternatives for reclaiming sodic soils, such a...
Permeability as an important parameter for radon risk classification of foundation soils
permeability radon soil gas transfer factor
2015/9/10
Permeability of soils and rocks for gases is one of the main parameters for final radon risk classification of building
sites. For the improvement of the method for radon risk classification it is re...
Degradation of Forest Soils in the Vicinity of an Industrial Zone
acidification contamination toxic elements
2015/7/28
Soils of the study area are acidified and the surface enrichment with Cd, Cu,
Pb, and Zn reflects anthropogenic contamination. Two forms of all PTEs were evaluated: potentially mobilized

Sorption of heavy metals in organic horizons of acid forest soils at low added concentrations
acidic soils adsorption desorption organic matter risk elements
2015/3/13
The individual adsorption/desorption of Cu, Pb, and Zn in six soil samples taken from organic horizons of acid forest soils is studied in batch experiments. These three metals were chosen because of t...
Modelling the impact of acid deposition on forest soils in North Bohemian Mountains with two dynamic models: the Very Simple Dynamic Model (VSD) and the Model of Acidification of Groundwater in Catchments (MAGIC)
