Understanding soil evaporation in reforestation processes in an area of extreme drought is important. We examined the effects of drip-irrigated, high-salinity groundwater on the formation of soil salt crusts and subsequent soil evaporation in the Taklimakan Desert Highway Shelterbelt. Soil evaporation was measured using micro-lysimeters (MLS, 20 cm in length × 10 cm in diameter), and chemical c...

This study investigated biodegradation of dibenzothiophene (DBT) in marsh soil spiked bywhite-rot fungus Phanerochaete chrysosporium. Soil samples were spiked with 100 ppm DBTand incubated at 30°C in a dark chamber for 30 days. Samples were evaluated for pH, Mnperoxidaseactivity, sulfate ion concentration and growth during the tests. Results showedmaximum levels of pH, Mn-peroxidase and sulfate...

Spatial scaling and determinism of the wide-scale distribution of macroorganism diversity has been largely demonstrated over a century. For microorganisms, and especially for soil bacteria, this fundamental question requires more thorough investigation, as little information has been reported to date. Here by applying the taxa-area relationship to the largest spatially explicit soil sampling av...

Indian is reticent source of medicinal and potential plants source and varieties of chemical substances. The narrow region of soil is directly influenced by root exudates used in rhizophere and associated soil micro organism. Recent studies have shown that, in natural ecosystems, plant diversity (Prober et al., 2015) and the genotypes of individual plants (Coats et al., 2014) can influence the ...
