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...
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)
air pollution Black Triangle historical deposition long-term modelling mass balance soil solution soil chemistry
2015/3/13
Enormous acid deposition that culminated in the 1970s contributed largely to accelerate the process of acidification of soils in northern Bohemia. As a consequence a wide forest decline occurred short...
Retention characteristics of acetochlor in soils collected from different depths in relation to soil properties (Žitny ostrov area, SW Slovakia)
chloroacetanilide herbicide desorption leaching potential sorption
2015/3/10
Determination of the sorption-desorption of herbicides within soil profile is one of the first steps in predicting their leaching potential. Batch experiments were performed to evaluate the influence ...
Systematic geochemical study of the soils, litter, and bedrock of a Permian limestone mountain, Central Japan
chemical composition enrichment factor nutrient plant
2015/3/9
The paper deals with the results of a systematic geochemical study of soils at Mt Kinshozan in Central Japan, a limestone area known for its well-preserved Permian fossils. Compared with the typical c...
Potassium fixation in soil size fractions of arid soils
calcareous soils Iran smectite soil fractionation
2015/3/9
Amounts of potassium (K) fixed in soil fractions of 10 calcareous soils of southern Iran were measured to evaluate the contributions of different soil size fractions to K fixation. Soil particles were...
Environmental impact of landfill on groundwater quality and agricultural soils in Nigeria
chemical land use parameters pollution wastes water
2015/3/5
Physical, chemical and bacteriological analyses were carried out of water samples from three boreholes located near a landfill, and or soil samples at Akure, Nigeria, to ascertain the effect of the du...
Persistent organochlorine pesticides and polychlorinated biphenyls in intensive agricultural soils from North India
accelerated solvent extraction (ASE) agricultural soil organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs)
2015/3/3
Organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) were determined in agricultural soils from the northern states of India. The average concentration of OCPs was 37.67 ± 0.33 ng/g (...
Wetting angle and water sorptivity in mineral soils
sub-critical repellency Washburn theory wavy capillary
2015/2/3
Two simple models of a non-cylindrical (wavy) capillary have been applied to show the impact of pore shape and of wetting angle on water sorptivity in soils. Wetting angle derived from the Washburn ap...

2015/1/30
In the territory of the Czech Republic there are more than 50% of agricultural soils exposed to water erosion; it is a very urgent problem both at present and for the future. It must be solved now whe...
Altitude and forest type effects on soils in the Jizera Mountains region
forest soils altitude forest type beech spruce elevation transects
2015/1/30
This paper is focused on the Jizera Mountains as a region strongly influenced by man in the past. The structure of the natural forest was changed. Species monocultures with similar tree ages were plan...
