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...
Land Use Changes and Sediment Yield on a Hilly Watershed in Central-East Argentina
GIS MUSLE soil loss territorial management
2015/7/28
Watershed management strategies need suitable techniques to be available in order to quantify sediment yield,
among other relevant issues. The aim of this work was to estimate the sediment yield on ...

The study deals with Volvi Lake, the second largest natural lake in Greece, where gradual alleviation and a
land use change have taken place in the last 60 years. The aim of the study was to estimat...
Soil pH changes in long-term field experiments with different fertilizing systems
acidification crop rotation mineral fertilization organic fertilization soil type
2015/3/13
The changes of soil pH in long-term 14-year field experiments with different fertilizing systems are described. The field experiments were located at four sites of the Czech Republic with different so...
Simulation of soil organic carbon changes in Slovak arable land and their environmental aspects
agricultural management long-term simulation RothC model soil organic carbon soil quality
2015/3/5
One of the key goals of the Thematic Strategy for Soil Protection is to maintain and improve soil organic carbon (SOC) stocks. A decline of SOC stocks is politically perceived as a serious threat to s...
Impacts of land use changes on soil erosion in Pa Deng sub-district, adjacent area of Kaeng Krachan National Park, Thailand
land cover land use changes soil erosion Universal Soil Loss Equation
2015/3/5
Soil erosion has been considered as the primary cause of soil degradation since soil erosion leads to the loss of topsoil and soil organic matters which are essential for the growing of plants. Land u...
Long-term changes in runoff from a small agricultural catchment
climate change Poland runoff variability small watershed trend analysis
2015/3/5
River runoff is an important indicator of environmental changes, which usually include climate and/or land use changes, and is also the basis of catchment water management. This study presents results...
Modelling soil organic carbon changes on arable land under climate change – a case study analysis of the Kočín farm in Slovakia
arable land climate change Kocín farm Slovakia soil organic carbon
2015/3/3
We have estimated soil organic carbon and crop yield changes under distinct climate change scenarios for the Kočín farm in Slovakia. Two regional climate change scenarios, i.e. the A2 and B2 SRES...
Changes of soil organic matter under minimum tillage in different soil-climatic conditions
