The current work aims to identifying the geomorphological, characteristics and classification of soils in some areas Ismailia governorate, Egypt. study area is located between longitudes 32o 06′ 45 22′ 30 E latitudes 30o 22' 57' 00 N. integration Remote Sensing (RS) Geographic Information System (GIS) techniques was used achieve this work. The geomorphic map produced by processing Landsat 8 i...

Even though many forest plants spend all or a significant portion of their lives in the forest understory, few studies have compared understory composition, structure, and resource availability among forests. We used standardized transect-based methods to compare small sapling densities (10–50 cm tall), understory vegetation cover, canopy openness, and nutrient availability in non-gap portions ...

The Lower Mississippian (Tournaisian) Ballagan Formation in SE Scotland yields tetrapod fossils that provide fresh insights into the critical period when these animals first moved onto land. The key to understanding the palaeoenvironments where they lived is a detailed analysis of the sedimentary architecture of this formation, one of the thickest and most completely documented examples of a co...

in order to study the effects of climate and geomorphology on the development of soils and their physico-chemical peroperties, two transects on the loess parent material were selected in two regions of golestanprovince. the regions were: huttan (maraveh tappeh area) and gorgan with aridic-thermic and xeric-thermic soil moisture and temperature regimes, respectively. four pedons in hutan and fiv...

this study was carried out in lorestan silakhoor plain  during 2001-2002. twenty soil properties from 25 profiles were evaluated. profiles studied were entisols and inceptisols. moreover, soil classification resulted in 5 subgroups, 8 families and 17 soil series. in the study, parametric land evaluation method was used. the strong correlation between the land index and observed yield (r = 0.55)...

Soils (Leptosols or Epileptic Regosols) with lithic contact at a depth of 50 cm occupy almost 20% the Brazilian semi-arid region. These soils are susceptible to erosion due faster saturation water-holding capacity during rainfall, which accelerates beginning runoff. However, traits in region Brazil less studied. The aim this study was characterize soil and landscape attributes areas Neossolos L...

this study was conducted to characterize the reactivity of carbonates in the surface horizons of 20 soils (entisols and aridisols) from central region of iran. the samples were analyzed for calcium carbonate equivalent (cce), active calcium carbonate equivalent (acce), non-active calcium carbonate equivalent (n.acce), carbonate mineralogy and surface area of carbonates (ssa) through n2 adsorpti...
