Nowadays, polluted soils are one of the primary environmental problems. Due to a large number oil-contaminated lands, new methods being developed more and actively, as well combination various existing for disposing oil spills. In this paper, bioremediation with use adsorption is considered reduce toxicity accelerate processes microbial destruction hydrocarbons. There selection sorbents based o...

BACKGROUND, AIM, AND SCOPE Diffusive gradients in thin films (DGT) have been recognized as a suitable tool to assess in situ metal bioavailability in soils. Mine tailings have some singular characteristics such as high heavy-metal concentrations, low pH, or absence of water retention capacity that may compromise the correct application of this technique whose applicability is known to be pH dep...

The aim of the study was to identify trends and dynamics changes in chemical biochemical properties soil induced by rotational grazing farmed deer. Soils pH content mineral nitrogen forms, total nitrogen, organic carbon were determined activity three enzymes. monitored soils slightly acidic neutral, with 1 mol KCldm−3 ranging from 6.37 7.03. contents carbon, range 9.42–19.37 gkg−1 1.13–2.24 gkg...

Statistical parameters of agro-gray soil varieties obtained on the basis generalization information are zero-monitoring cycle in studied region and serve as reliable criteria for diagnosis these soils. Numerical indicators reflect results past current processes. In agricultural production, role arable layer with all properties that determine level grain yield is especially important. Thus, vari...

Arsenic is a natural trace element found in the environment. In some cases and places, human activities have increased the soil concentration of As to levels that exceed hazard thresholds. Amongst the main contributing sources of As contamination of soil and water are the following: geologic origin, pyriticmining, agriculture, and coal burning. Arsenic speciation in soils occurs and is relative...

all of the tea plantations in iran are concentrated in the caspian sea region on soils previously developed under deciduous natural forests. this research conducted to study the effect of land use change (from forest to tea) on selected physico-chemical and mineralogical properties of soils under humid climate and mountainous landscape in northern iran. three transects facing west to northwest ...

We sampled shrub canopy volume (height times area) and environmental factors (soil wetness, soil depth of thaw, soil pH, mean July air temperature, and typical date of spring snow loss) on 471 plots across five National Park Service units in northern Alaska. Our goal was to determine the environments where tall shrubs thrive and use this information to predict the location of future shrub expan...
