copper environmental loads soil enzymes soil and water pollution toxic elements
2015/3/10
Contamination of soil and water environment by heavy metals in a former mining area and their effect on the soil characteristics were determined. Soil samples were collected in the village of Rudňany ...
Effect of agricultural lands afforestation and tree species composition on the soil reaction, total organic carbon and nitrogen content in the uppermost mineral soil profile
acidification afforestation carbon nitrogen soil reaction
2015/3/10
Forests occupy one third of the world’s land area and govern carbon (C) transfers and influence nitrogen (N) content in the biosphere. Afforestation leads to soil changes of specific dynamics, often a...
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...

2015/3/2
In average samples of three sandy-loamy acid Cambisols from a South Bohemian area labile organic matters were determined by the permangate method modified by the dichromate method, and the rate consta...
Laboratory assay of aluminium transport through intact soil sample under controlled conditions
aluminium transport forest soils forest type percolation experiment soil acidification
2015/3/2
Aluminium (Al) mobilisation in the forest soils is a serious problem due to the soil acidification. The rate and magnitude of leaching of Al and other elements and compounds from soils can be examined...
