Middle and southern Iraq suffers from polluted soils due to crude oil, spilled on land, leakage from transmitting pipe networks, or petroleum products from refineries. Many researchers have studied pollution impacts on the soil in details, but there is a clear lack of investigation on the influence of crude oil on soil erodibility. Recent researches have investigated the influence of pollution ...

Equations used to calculate erodibility in the Water Erosion Prediction Project soil erosion Ž . model WEPP are based on erodibility studies in the USA and may not function well in another Ž . region. This study was conducted to: i analyze erodibility and infiltration characteristics of some Ž . predominant soils of southern Spain, and ii test equations used to calculate interrill erodibility i...

The overall goal of this research is to compare the effects of woody and herbaceous vegetation on stream bank erosion. This chapter presents the third of three substudies that address the impact of vegetation on stream bank erosion. The goal of this study was to determine the erodibility of rooted stream bank soils and to evaluate the relative effects of vegetation type, root density, and freez...

ABSTRACT: Overall plant growth and microbial biomass can be effected by dust accumulation. The chloroform fumigation-extraction method was used to evaluating the effect of cement dust pollution emitted from Kurdistan cement factory on soil microbial biomass carbon. Chlorophyll content (a, b and total) of plants species was measured in different distance from cement factory. Mic...

Growth performance and heavy metal uptake by willow (Salix viminalis) from strongly and moderately polluted calcareous soils were investigated in field and growth chamber trials to assess the suitability of willow for phytoremediation. Field uptakes were 2-10 times higher than growth chamber uptakes. Despite high concentrations of cadmium (>/=80 mg/kg) and zinc (>/=3000 mg/kg) in leaves of will...

introduction: globally, soil erosion is a principal degradation process resulting in negative impacts on different soil functions (food and other biomass production, water storing, filtering and transformation, habitat and gene pool, physical and cultural environment for mankind, and source of raw materials) which ultimately causes irreversible effect on the poorly renewable soil resource. dete...
