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
field soil description fuzzy k-means pedometrics regression-kriging terrain
<
2015/3/9
We tested the performance of a formalized digital soil mapping (DSM) approach comprising fuzzy k-means (FKM) classification and regression-kriging to produce soil type maps from a fine-scale soil obse...
HYPRESCZ - database of soil hydrophysical properties in the Czech Republic
HYPRES pedotransfer functions soil water retention curve

A set of fifty samples were taken from soil surface layers of an anonymous vineyard in the Bohemia region of the Czech Republic. Samples were analysed for basic soil parameters including pH and humus ...
Soil organic carbon dynamics and its influence on the soil erodibility factor
agrotechnical erosion control measures soil erodibility factor soil erosion soil organic carbon
<
2015/3/5
The effect of erosion and erosion control measures on changes in the amount of organic matter in soil was studied. We investigated the influence of organic matter inputs into the soil on surface runof...
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...
Effects of soil depth spatial variation on runoff simulation, using the Limburg Soil Erosion Model (LISEM), a case study in Faucon catchment, France
conditional simulation Faucon hydrograph kriging LISEM soil depth
<
2015/3/5
Soil depth is an important parameter for models of surface runoff. Commonly used models require not only accurate estimates of the parameter but also its realistic spatial distribution. The objective ...
