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...
Evaluation of ground penetrating radar and vertical electrical sounding methods to determine soil horizons and bedrock at the locality Dehtare

2015/3/9
Recently, geophysical methods have been widely used in many fields including pedology. Two of them, ground penetrating radar (GPR) and vertical electrical sounding (VES) were employed at the Dehtá"...
Temporal variations of runoff and sediment in different soil clay contents using simulated conditions
clay erosion plot rainfall simulator
<
2015/3/9
Soil clay content (SCC) plays an essential role in the processes of infiltration, seal and crust formation, runoff, and soil erosion. The role played by SCC in water erosion has received much attentio...
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...
Assessment of a soil with moderate level of contamination using lettuce seed assay and terrestrial isopods assimilation assay
Lactuca sativa short-term bioassays soil contamination woodlice
<
2015/3/9
Lettuce (Lactuca sativa) seeds play a significant role in toxicity tests of isolated chemicals, pesticides, and environmental samples. Commonly, the main variables under study are the rate of seed ger...
Assessment of trace and heavy metal distribution by four sequential extraction procedures in a contaminated soil
fractionation metals mining activities pollution
<
2015/3/9
Four sequential extraction procedures (Sposito, Tessier, Silveira and Bureau Communautaire de Reference (BCR)) were used to evaluate the distribution of some metals (Fe, Cu, Cd and Zn) in a contaminat...
Digital soil mapping from conventional field soil observations
