Spatial and temporal variability in soil CO2-C emissions and relation to soil temperature at King George Island, maritime Antarctica
(2010-12-01)
Few studies have examined the effects of temperature on spatial and temporal trends in soil CO2-C emissions in Antarctica. In this work, we present in situ measurements of CO2-C emissions and assess their relation with ...
Cover crops and no-till effects on physical fractions of soil organic matter
(2013-06-01)
Physical fractions (free light fraction, intra-aggregate light fraction and heavy fraction) of soil organic matter (SOM) are good indicators of soil quality for sustainable land use. The objective of this study was to ...

Soil CO2 efflux following rotary tillage of a tropical soil
(Elsevier B.V., 2005-12-01)
Stopping the increase of atmospheric CO2 level is an important task and information on how to implement adjustments on tillage practices could help lower Soil CO2 emissions would be helpful. We describe how rotary tiller ...

Spatial Variability of Soil Organic Matter and Cation Exchange Capacity in an Oxisol under Different Land Uses
(2016-12-30)
Soil properties may exhibit large spatial variability. Frequently this variability is auto-correlated at a certain scale. In addition to soil-forming factors, soil management, land cover, and agricultural system may affect ...
Potential use of the veris apparent EC sensor to predict soil texture under the semi-arid conditions of central Arizona
(2009-12-01)
The operational details of the apparent electrical conductivity (ECa) sensor manufactured by Veris Technologies have been extensively documented in literature reports, but the geographical distribution of these research ...

Revisiting Classical Methods to Identify Collapsible Soils
(Brazilian Soc Soil Mechanics & Geotechnical Engineering, 2015-09-01)
The paper revisits and updates two expedite methods used to identify the occurrence of collapsible soils. The methods were proposed by Gibbs (1961) and de Mello (1973) and have in common the assumption that collapsible ...
Carbon Stocks and Isotopic Composition of the Organic Matter in Soils Covered by Native Vegetation and Pasture in Sorocaba, SP, Brazil
(Univ Tehran, 2009-06-01)
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 ...
