Vertical distribution of phosphorus in agricultural drainage ditch soils.
Pedological processes such as gleization and organic matter accumulation may affect the vertical distribution of P within agricultural drainage ditch soils. The objective of this study was to assess the vertical distribution of P as a function of horizonation in ditch soils at the University of Maryland Eastern Shore Research Farm in Princess Anne, Maryland. Twenty-one profiles were sampled fro...

ویژگی های زمین شیمیایی، کانی شناسی، و میکرومورفولوژیکی خاک ها و سنگ مادر مربوطه در منطقه بین بخش های جنوبی زاگرس و خلیج فارس تا دریای عمان(استان هرمزگان، ایران) مورد بررسی قرار گرفت. هدف های این مطالعه شناسایی تغییرات در خصوصیات فیزیکی، شیمیایی، و ترکیب کانی شناسی خاک، مطالعه میکرومورفولوژی و تکامل خاک، و بررسی توزیع عنصر خاک بر اساس هوازدگی، پروسه های خاک و زمین شناسی جهت توصیف اثرات مواد مادر...
15 صفحه اولPreliminary study on vertical distribution of microorganisms in the Bannock Basin waters (Eastern Mediterranean Sea)
Preliminary data are presented on microbial distribution in the Bannock Basin, a hypersaline and anoxic depression in the lower 3300 m of the water column. Epifluorescence microscopy was suitable for a first approach to enumeration of the microbial mass in water samples from this peculiar marine environment. Progressive increase in total microbial numbers occurs in the anoxic layer, with the hi...
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 کاملSubgingival Distribution of Microorganisms
Composition of subgingival microbiotas has long been seen as being of primary importance in the etiology of periodontal diseases. Development of advanced molecular methods has improved our knowledge about the role of traditional periodontal pathogens as well as resulted in the recovery of novel pathogen candidates. Detection rates of these microorganisms vary considerably between geographical r...
