Natural soils have been polluted by variety of human activity such as urbanization, industrialization and excessive fertilizer pesticide usage. However, the agricultural alongside highways, especially those international ones, are relatively at higher risk heavy metal pollution depending on intensive track traffic. Therefore, total 72 soil samples from 24 sampling sites were taken 5 km interval...

An appropriate fertilization strategy is essential for improving micronutrient supply, crop nutrition, yield and quality. Comparative effects of different application strategies fertilizer were evaluated in two contrasting sites/soils (upper slope Chernozem lower Solonetz) within a farm field located the Brown soil zone Saskatchewan, Canada. The study objective was to examine impact Cu, Zn, B o...

Acidic soils need to be improved of pH in order maintian sustainable agricultural production. In ameliorate the pH, lime, available Ca and some other properties acidic soils, materials that increase soil value are needed. One these organic substances is gyttja. Gyttja contains 30-40% CaCO3 40-50% matter, which generated as waste Af?in Elbistan thermal power plant its reserve estimated 4.8 billi...

Extractable functions are functions where any adversary that outputs a point in the range of the function is guaranteed to “know” a corresponding preimage. Here, knowledge is captured by the existence of an efficient extractor that recovers the preimage from the internal state of the adversary. Extractability of functions was defined by the authors (ICALP’08) in the context of perfectly one-way...

Metal immobilization may contribute to the environmental management strategy of dredged sediment landfill sites contaminated by metals. In a field experiment, amendment effects and efficiency were investigated, focusing on plants, springtails and bacteria colonisation, metal extractability and sediment ecotoxicity. Conversely to hydroxylapatite (HA, 3% DW), the addition of Thomas Basic Slag (TB...

Few experiments in the coastal plain region of the southeastern United States have reported the effect of long-term tillage and tillage intensity on chemical soil quality indicators. The purpose of this study was to determine the 17-year influence of four tillage systems on chemical soil quality indicators in a Benndale fine sandy loam (coarse-loamy, siliceous, semiactive, thermic, Typic Paleud...

17 To assess the risks that contaminated soils pose to the environment properly a greater 18 understanding of how soil biota influence the mobility of metal(loid)s in soils is 19 required. Lumbricus terrestris L. were incubated in three soils contaminated with As, 20 Cu, Pb and Zn. The concentration and speciation of metal(loid)s in pore waters and the 21 mobility and partitioning in casts were...
