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...
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...
Impact of water quality, cultivation, and cropping systems on infiltration and physical properties of an arid clay soil
aggregate stability crop cover infiltration tillage wastewater
2015/3/10
Irrigation with treated wastewater is essential for increasing crop production in arid and semi arid regions. Field experiments were conducted on rainfed clayey soil to investigate the impact of water...
The impact of vegetation on the bank erosion (Case study: The Haraz River)
GIS hydraulic behaviour HEC-RA roughne coefficient
2015/3/9
Vegetation establishment is a suitable biological method of erosion control. Bank erosion is one form of water erosion and its adverse effects include an increase in turbidity, degradation of riverban...
Surface runoff simulation to mitigate the impact of soil erosion, case study of Třebsín (Czech Republic)
hydrological model shear stress shear velocity soil loss
2015/3/5
The relation between soil erosion and its redistribution on land strictly depends on the process of surface runoff formation during intensive rainfall. Therefore, interrupting and reducing continuous ...
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...
Impact of Arable Land to Grassland Conversion on the Vegetation-period Water Balance of a Small Agricultural Catchment (Němčicky Stream)
