RWEQ-Wind erosion predictions for variable soil roughness conditions
(Elsevier, 2016-03)
The soil surface roughness is a main factor in all wind erosion prediction models, including the Revised Wind Erosion Equation (RWEQ). The objective of this study was to test the erodibility of two typical soils of the ...
Factors affecting phosphorus sorption in loess soils of the semiarid Argentina
(Pisa University Press, 2000-08)
Previous results showed that phosphorus sorption strongly correlated with contents of active Al and Fe oxides and organic matter (OM) in soils of the-Semiarid Argentinean Pampas. Objective of this study was to determine ...
Late Quaternary paleosols, stratigraphy and landscape evolution in the Northern Pampa, Argentina
(Academic Press Inc Elsevier Science, 2006-07)
The field properties, micromorphology, grain-size, geochemistry, and optically stimulated luminescence (OSL) ages of two late Quaternary sections have been used to reconstruct the sequence of pedosedimentary processes and ...
Degradation of the soil surface roughness by rainfall in two loess soils
(Elsevier Science, 2011-08)
The soil surface roughness is one of the main factors affecting wind erosion. Little is known about the influence of rains on the degradation rate of the soil surface roughness in different tillage systems and soil types. ...
Impacts of land-use pattern on soil water-content variability on the Loess Plateau of China
(TAYLOR & FRANCIS AS, 2010)
Long-term vegetation restoration carried out on the slopes of the Loess Plateau of China employed different spatial and temporal land-use patterns but very little is known about the effects of these patterns on soil ...
Effect of landscape position on the acidification of loess-derived soils under Pinus radiata
(Wiley Blackwell Publishing, Inc, 2007-08)
Interactions between landscape position and the acidifying effect of trees planted into loess-derived grassland soils were studied in the Ventana region of Argentina. Forests of Pinus radiata planted at the end of 1940, ...
Geochemistry of a soil catena developed from loess deposits in a semiarid environment, Sierra Chica de Córdoba, central Argentina
(Elsevier Science, 2017-06)
A catenary sequence of soils formed on reworked loess under semiarid climatic conditions was studied. Four soil profiles located on the piedmont of Sierra Chica de Córdoba, central Argentina,were described, classified and ...
Influence of sand gradation on compaction of loess soils
(Elsevier Science, 2020-02)
Assessing the interaction among soil organic carbon (OC), Atterberg limits and soil texture, especially sand gradation, in maximum bulk density (BDMAX) can improve prediction of soil compactibility. Our objectives were a) ...
Control factors of the spatial distribution of arsenic and other associated elements in loess soils and waters of the southern Pampa (Argentina)
(Elsevier Science, 2016-05)
Surface and groundwaters of El Divisorio brook (Argentina) have excessive As (WHO, USEPA, CAA: > 10 μg L− 1). The rural population is at risk of arsenicism because groundwater is the only source of water for human consumption. ...
Environmental changes in the pre-Andean valleys and Chaco Plain (Northwest Argentina) during the Late Pleistocene and Holocene
(E Schweizerbartsche Verlags, 2005-08)
Thick loess deposits interbedded with paleosols in the intermountain valleys of Tafí (Tucumán province) and Balcozna (Catamarca province) in north-western Argentina were assigned to late Pleistocene age on the basis of ...
