Carbon dioxide emission related to chemical properties of a tropical bare soil
(Elsevier B.V., 2000-09-01)
In this work the relationship between CO2 emissions and the soil properties of a tropical Brazilian bare soil was investigated. Carbon dioxide emissions were measured on three different days at different soil temperature ...
Spatial and temporal variability in soil CO2-C emissions and relation to soil temperature at King George Island, maritime Antarctica
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 ...
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 ...
Aspects of Mechanical Behavior and Modeling of a Tropical Unsaturated Soil
The research studies the applicability of two elastoplastic models for the collapse prediction of the lateritic soil profile from Southeastern Brazil. These tropical soils have peculiar geotechnical behavior, due to their ...
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 ...
Digital soil mapping and GlobalSoilMap. Main advances and ways forward
In this concluding paper, we summarize the main advances coming forward from the joint conference of the International Union of Soil Sciences (IUSS) Working Groups (WG) "Digital Soil mapping" (DSM) and "GlobalSoilMap". We ...
Concentrations of Cu, Fe, Mn, and Zn in tropical soils amended with sewage sludge and composted sewage sludge
Sewage sludge may be used as an agricultural fertilizer, but the practice has been criticized because sludge may contain trace elements and pathogens. The aim of this study was to compare the effectiveness of total and ...
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 ...
Medicinal Mushroom Growth as Affected by Non-Axenic Casing Soil
(Science China Press, 2011-04-01)
Ten different casing soils were collected from two soils at two depths (0.2 and 2.0 m below soil surface) to examine the relationships between the physical properties of non-axenic casing soil and yield, number and weight ...
