Zinc (Zn) availability and mobility in soils is controlled by its interaction with the soil matrix and amendments. Contradicting evidence has been reported for factors influencing Zn behavior in soils. The aim of this study was to investigate the Zn sorption in selected acid, calcareous and gypsiferous soils with different background electrolytes (Na+, K+ and H2PO4, NO3 and Cl backgrounds). Iso...

soil, a 3-dimensional component of the landscape, or simply a natural body in a soilscape with a given geopedological setting, was modeled by jenny as s = f (climate, organism, relief, parent material, time). to map such a complex body, the concept ‗pedon’ –the smallest volume that can be recognized as a soil had to be defined. classically, soil is known to function as provider, controller, reg...

land cover change constitutes one of main way of alteration of soil organic matter in both quantitative and qualitative terms. the goal of this study was to compare the carbon stock and the isotopic signature of the organic matter in the soil of areas with different land use, covered with forest and grass (pasture). the study area is located at sorocaba, sp, brazil. using un-deformed soil sampl...

Precipitation in northern Chile is controlled by two great wind belts—the southern westerlies over the southern Atacama and points south (> 24 S) and the tropical easterlies over the northern and central Atacama Desert (16–24 S). At the intersection of these summer and winter rainfall regimes, respectively, is a Mars-like landscape consisting of expansive surfaces devoid of vegetation (i.e. abs...

This paper presents the second and third stages of a multivariate taphonomic analysis of the bovid bone assemblage from Dunefield Midden (DFM), a Later Stone Age site on South Africa’s west coast. The second stage investigates bovid skeletal element abundance and longbone fragmentation patterns at the site. The third stage integrates these data with bone modification data (Stewart 2010) to expl...
