Assessment the effect of Slope aspect and position on some soil microbial indices in rangeland and forest

Extended abstract   Introduction   Topography is one of the effective factors in soil formation and development. Topographical features such as slope aspect and position, by affecting soil temperature, evaporation capacity, soil moisture content, soil organic matter, precipitation, movement, and accumulation of soil solution can impress soil microbial properties. For investigating the ...

Comparison of temperature effects on soil respiration and bacterial and fungal growth rates.

Temperature is an important factor regulating microbial activity and shaping the soil microbial community. Little is known, however, on how temperature affects the most important groups of the soil microorganisms, the bacteria and the fungi, in situ. We have therefore measured the instantaneous total activity (respiration rate), bacterial activity (growth rate as thymidine incorporation rate) a...

اثر شوری بر برخی شاخص‌های میکروبی خاک در حضور و عدم حضور ریشه‌های زنده گیاه

Similar to plants, soil salinity may reduce microbial growth and activities in different ways. The aim of this study was to determine the effects of different levels of salinity on some microbial indices in the presence and absence of plant's living roots. In this study, five levels of salinity using NaCl, CaCl2, MgCl2 and KCl and three soil media (soil with no plant, soil cultivated with wheat...

Synthesis and Characterization of ZnO Nanostructures Grown via a Novel Atmospheric Pressure Solution Evaporation Method

In this study, a novel method called “atmospheric pressure solution evaporation (APSE)” wasdeveloped for growing of Zinc Oxide (ZnO) nanostructures on Al2O3 surface. Zinc acetate dihydrate,Polyvinyl Pyrrolidone, and deionized water were used as precursor, capping, and solvent, respectively.The growth of ZnO nanostructures from evaporated solution was performed at three temperatures of300, 400, ...
