Geochemical characterization of the forest loess soils along a precipitation gradient in Northern Iran
Introduction: The loess-paleosol sequences in Northern Iran are important archives represent several cycles of Quaternary climate change and can be used to complete the information gap on loess between Europe and central Asia. Loess geochemistry reflects paleoweathering conditions and it can be used to determine the nature and provenance of loess deposits. In the Caspian Lowlands, a pronounced...
متن کاملInfluences of soil acidity on Streptomyces populations inhabiting forest soils.
The Streptomyces populations inhabiting five acidic forest soils were examined. It was found that lowering the pH of a medium selective for streptomycetes (starch-casein agar) to the pH of the particular soil horizon being plated influenced both the total numbers and types of streptomycetes that were isolated from the soils examined in this study. On the acidified medium both the numbers of str...
متن کاملDistribution of radionuclide in the forest soils (Western Ghats-India)
Background: The presence of radionuclides in the soil, measures need to be taken to minimize the radiation dose to humans. It is mostly gamma-emitting radionuclides that contribute to the radiation dose in long term behavior of these radionuclides in soil may determine the extent to which such countermeasures need to be applied. Materials and Methods: The activity concentration of these radionu...
متن کاملGeochemical Analysis of Soil Physicochemical Properties and Heavy Metals Content in the Long- term Wastewater-irrigated Soils
Exploring the homogenous regions for site specific management is important, especially in the areas under different anthropogenic activities. This was investigated using multi-way analysis including Factor Analysis, Hierarchical Clustering Analysis and k means in the areas under long-term wastewater irrigation over a period of more than 40 years, in Shahre Rey, south of Tehran. By using Factor ...
متن کاملLong-term forest soil warming alters microbial communities in temperate forest soils
Soil microbes are major drivers of soil carbon cycling, yet we lack an understanding of how climate warming will affect microbial communities. Three ongoing field studies at the Harvard Forest Long-term Ecological Research (LTER) site (Petersham, MA) have warmed soils 5°C above ambient temperatures for 5, 8, and 20 years. We used this chronosequence to test the hypothesis that soil microbial co...
