Abstract. Soil hydrologic processes play an important role in the hydro-pedo-geomorphological feedback cycle of landscape evolution. properties and subsurface flow paths both change over time, but due to a lack observations, water are often not properly represented soil evolution models. We investigated across chronosequence calcareous glacier forefield at Griessfirn Swiss Alps. Young soils dev...
Since the 60’s, many authors have reported presence of common silt-sized materials in Ebro valley, on surface formations and positions that given rise to several interpretations, sometimes contradictory. According references, three main terms are used (gypsiferous silts, loess flour-like gypsum) applied silts fine sands with gypsum accumulations. The two first carbonate contents up 40-50%, coar...
Agriculture is a globally dominating land use, so efforts to restore soil organic carbon (C) and nitrogen (N) lost through historical degradation could have enormous benefits production the environment, particularly by storing an reserve of nutrients in avoiding return small portion biologically cycling C atmosphere. Estimates N storage from conservation agricultural management are still limite...
A new burnetiamorph therapsid, Isengops luangwensis , gen. et sp. nov., is described on the basis of a partial skull from upper Madumabisa Mudstone Formation Luangwa Basin northeastern Zambia. diagnosed by reduced palatal dentition, ridge-like palatine-pterygoid boss, exposure jugal that extends far anteriorly, tall trigonal pyramid-shaped supraorbital and recess along dorsal margin lateral tem...
Mirak (Semnan, Iran) is a Paleolithic site located in a dry floodplain near the northern edge of the Iranian Central Desert. The pedo-sedimentary successions of Mirak 8 are deposited from late Pleistocene to Late Holocene,. The chronological framework was established using optically stimulated luminescence (OSL) dating. The oldest studied units dating back to ~50 ± 3.0 ka. Within this stratigra...
• Three main vertical patterns for Hg distribution were observed in ten podzolic soils. Organic matter dynamics and podzolization influenced the observed. The more intense is podzolization, accumulates illuvial horizons. Total organic mainly accounted accumulation surface Al-humus complexes Fe compounds contents Soils are reservoir terrestrial ecosystems where it deposited via wet or dry deposi...
Review of npg-2015-79 This manuscript presents multifractal analyses of nitrogen adsorption and desorption isotherms obtained on soil samples from 6 different soil profiles in São Paulo State, Brazil. There is very little that is new here, and the manuscript essentially repeats the study by Paz-Ferreiro et al. (2013), but in a different geographic area and with some less clayey soils. Although ...
