Mathematical modelling of temperature profile of volcanic soils affected by an external thermal impact
(CSIRO PUBLISHING, 2006)
In this work, the soil temperature at depth was measured in the laboratory, and a mathematical model to fit the temperature pro. le in volcanic soils classified as Ultisols and Andisols was used. The mathematical model ...
Hierarchy of factors driving N2O emissions in non-tilled soils under different crops
(Wiley, 2013-08)
Nitrous oxide (N2O) is emitted to the atmosphere as a by-product of nitrification and denitrification by soil microbial processes. Differences in climate, soil and management regulate these processes, causing N2O emissions ...
Temperatura e umidade de um solo franco arenoso cultivado com milho
(Universidade Federal de Santa MariaBRAgronomiaUFSMPrograma de Pós-Graduação em Ciência do Solo, 2010-03-01)
Water is a key factor for crop yields, and causes major fluctuations in productivity, especially for maize cultivated in southern Brazil. Mulching the soil surface, temperature and soil moisture are factors closely linked ...
Thermal treatment of soils contaminated with gas oil: Influence of soil composition and treatment temperature
(Elsevier Science, 2002-10)
Samples of two soils containing different organic matter contents, neat or contaminated with gas oil (diesel fuel oil) at 2.5wt.% were heated from room temperature to different final temperatures (200-900°C). The experiments, ...
Thermal inactivation of Phytophthora nicotianae
(2000-01-01)
Phytophthora nicotianae was added to pasteurized soil at the rate of 500 laboratory-produced chlamydospores per gram of soil and exposed to temperatures ranging from 35 to 53°C for 20 days. The time required to reduce soil ...

Short-term temporal changes in the spatial variability model of CO2 emissions from a Brazilian bare soil
(Elsevier B.V., 2000-09-01)
In this work, the spatial variability model of CO2 emissions and soil properties of a Brazilian bare soil were investigated. Carbon dioxide emissions were measured on three different days at contrasted soil temperature and ...

Soil respiration in Patagonian semiarid grasslands under contrasting environmental and use conditions
(Elsevier, 2015-08)
Grasslands comprise 85% of Southern Patagonia land area and play a critical role in the global carbon
cycle. We evaluated seasonal dynamics to identify differences in soil respiration rates between contrasting
grasslands ...
Short-Term Soil CO2 Emission and Soil Attributes Under Contrasting Sugarcane Cultivars
(2018-01-29)
Agriculture is a great emission source of CO2 into the atmosphere, contributing significantly to the greenhouse effect. Considering the hypothesis that there are differences in soil carbon dynamics due to the distinct ...
