Loess is a main archive of Pleistocene landscapes and environments therefore has an important connection to the preservation interpretation Paleolithic sites. In Europe, anthropogenic sites have been found in loess because past local occupation. At one extreme, are well preserved with minimal disturbance often accompanied by embedded proxies estimate ecological parameters. On other hand, deposi...
This study aims to analyze the physical properties of soil, such as texture, color, temperature, moisture content, bulk density and permeability well magnetic soil under a tree stand cashew, coconut cocoa. research was conducted on mixed farms where there are cocoa trees close each other. Samples were taken vertically from top depth 100 cm. The results showed that color texture tended be same c...
The aim of the work described here was to understand pedogeochemical signature five rare earth elements (REEs; Ce, Nd, La, Y, and Sc) in vineyard soils Campo de Calatrava (a unique territory with calcareous, volcanic metamorphic rocks). mean contents surface horizons Sc were 65.7, 32.0, 35.5, 18.8, 13.9 mg·kg–1, respectively. In subsurface Ce 62.8, Nd 31.1, La 35.7, Y 17.9, 14.4 mg·kg–1. result...
Vegetated mounds are an important geomorphological feature of the Pantanal, where the influence of floods dictates not only hydropedological processes, but also the distribution and ecology of the flora and fauna. This work aimed to identify factors and processes that influence the formation and spatial distribution of the mounds, which are commonly associated with termite activity. In order to...
Analysis of stacked Permo-Pennsylvanian palaeosols from north-central Texas documents the influence of palaeolandscape position on pedogenesis in aggradational depositional settings. Palaeosols of the Eastern shelf of the Midland basin exhibit stratigraphic trends in the distribution of soil horizons, structure, rooting density, clay mineralogy and colour that record long-term changes in soil-f...
