Sulfate desorption and mobility in soil can be of both environmental and agronomic importance. This study was conducted to describe the desorption of SO 4 from agricultural soils under experimental conditions applicable to the movement of SO 4 in overland flow and runoff waters. The kinetics of SO 4 desorption from soil were investigated at five different water/soil ratios (10:1-400:1), five ti...

A laboratory study was carried out to evaluate the protective role of ectomycorrhizal fungi against contamination of plants growing in soil treated with cadmium at a dose of 150 μg Cd/ g soil. An alginateimmobilized inoculum of mycorrhizal fungi was used to introduce the fungi to the soil. The impact of fungi was examined in terms of changes in cadmium levels in inoculated and non-inoculated se...

Adsorption and desorption kinetics of Hg(II) on four soils at pH 6 were investigated to discern the mechanisms controlling the retention and release reaction rates of Hg(II) on soil. A stirred-flow method was employed to perform experiments. Apparent adsorption and desorption rate coefficients were determined by a one-site second-order kinetic model. Both adsorption and desorption were characte...

environmental problems associated with the excessive use of chemical fertilizers and abiotic stresses due to soil pollution by heavy metals have encouraged use of biological fertilizers in modern agriculture. in order to protect environment and reduce the tension caused by heavy metals, it is essential to use biofertilizer in crop production. to assess the effects of biofertilizers on yield and...

make better predictions about the mobility of contaminants, it is critical that time-dependent metal sorption To improve predictions of the toxicity and threat from Pb contamiand desorption behavior on soil be understood, as well nated soil, it is critical that time-dependent sorption and desorption behavior be understood. In this paper, the sorption and desorption as the mechanism of the sorpt...

The effective management of sewage sludge materials in an environmentally and economically acceptable way is through the pyrolytic conversion of the sludge to biochar and its use for agricultural purposes. The aims of this work were: (1) to assess the effect of biochar prepared from sewage sludge at two different temperatures (350 ºC and 650 ºC) on the adsorption/desorptio...
