Textural features are widespread in many soils, provide pedogenetic evidence, and fundamental soil classification systems. The presence of these their conservation over time require certain processes forming factors. This study investigates the genesis textural pedofeatures, especially clay coatings, stressful conditions that can eventually lead to disappearance. To achieve this goal, four prof...

in this study, micromorphological properties of some samples collected from pedons polluted with petroleum refinery wastes and some adjacent unpolluted pedons were studied. after description of the studied pedons, disturbed and undisturbed samples were collected for physicochemical and micromorphological analyses. the results showed that the physicochemical properties (i.e. structure, bulk dens...

development of argillic horizon in loess derived soils under xeric and udic soil moisture regimes was studied in golestan province. soils were classified as hapludalfs and haploxeralfs. high leaching, stability of the surface, forest vegetation,structure and well drainage conditions provide appropriate conditions for clay migration through the profile and formation of argillic horizons. in the ...

in order to comparision of the micromorphic properties of saline-sodic and nonsaline-nonsodic soils in the west of urmia lake, four soil profiles (2profile in saline-sodic soils and 2profiles in nonsaline-nonsodic soils) were investigated. these profiles were described and sampled using standard methods. soil samples were used for physico chemical analysis and undisturbed and oriented samples w...

In the Eastern Mediterranean, where some of earliest known urban cities are located, relatively little is about soils in archaeological contexts. Red Mediterranean Soil (RMS) a hallmark region while impact long-term urbanization on RMS material understudied. this article we present evidence from longue durée cityscape Jerash, Jordan, to determine how humans have used, modified and impacted an c...

Volume 2 consists of 11 chapters in which the distribution, land-use and management of red and lateritic soils of India, Sri Lanka, Bangladesh, Nepal, The Philippines, Vietnam, Kenya, Argentina and Bulgaria are described. There is some overlap with information on the Indian soils presented in volume 1, but the soil information on the other countries is stimulating reading. The internaŽ . tional...
