Loss of pesticide efficacy resulting from enhanced rates of microbial degradation has been observed with several pesticides including the insecticide carbofuran (2,3-dihydro-2,2-dimethyl-7-benzofuranyl methylcarbamate). Soils in which this phenomenon occurs are often referred to as "problem soils." Several previous studies have documented the temporal aspects of the conversion of a nonproblem s...

To secure adequate food supply is the major challenge for humanity in the 21st century. Growing world population andits urbanization put pressure on this basic need, which is further threatened by the constant loss of fertile land. Theassessment of sustainability of food supply under increasing pressure on land resources has been selected as one of themost important priority topics ...

The rapid growth in population and industrialization cause generation of large quantities of effluents. The bulk effluents generated from industrial activities are discharged either treated or untreated over the soil leading to changes in soil properties causing improvement or degradation of engineering behaviour of soil. If there is an improvement in engineering behaviour of soil, there is a v...

max 200 words) Soil biota are essential for many soil processes and functions, yet there is an increasing pressure on soil biodiversity and soil degradation remains a pertinent issue. Therefore, the sustainable management of soils requires soil monitoring, including biological indicators able to relate land use and management to soil functioning and ecosystem services. Since the 1990’s, biologi...

Soils are essential to life on Earth but rapidly degrading worldwide due unsustainable human activities. We argue that soil degradation constitutes a key system process should be added the planetary boundaries framework.

effect of different concentrations of ammonium chloride (ncl) and ammonium nitrate (nn)and surfactants such as tween-80, hpcd and rhamnolipids on the bioremediation of pahs and ocps wasinvestigated. the results showed that the best optimum concentration of ncl and nn was 50 g·kg-1, and thepahs degradation rate during 60 days of remediation was enhanced to 64.6% and 62.8% for ncl and nn,respecti...

A rhizobox experiment was conducted to investigate degradation of decabromodiphenyl ether (BDE-209) in the rhizosphere of ryegrass and the influence of root colonization with an arbuscular mycorrhizal (AM) fungus. BDE-209 dissipation in soil varied with its proximity to the roots and was enhanced by AM inoculation. A negative correlation (P < 0.001, R(2) = 0.66) was found between the residual B...

classification and utilization of lands based on their capability are necessary for sustainable land use management. the purpose of this study was to identify and grade the effective qualities on the rainfed farming in the roin area, north khorasan province, during the year of 2011. based on field observations and literature review the land qualities including climate, rooting conditions, moist...
