Surface application of biosolids in the Chihuahuan Desert: Effects on soil physical properties
(Taylor & Francis, 2001-12)
Biosolids (anaerobically digested sewage sludge) have been applied to agricultural lands for many years and more recently to rangelands as a soil amendment to add plant macro and micronutrients and organic matter to the ...
Medição e simulação da temperatura e conteúdo de água em argissolo sob resíduos de aveia
(Universidade Federal de Santa MariaBrasilAgronomiaUFSMPrograma de Pós-Graduação em Ciência do SoloCentro de Ciências Rurais, 2017-01-27)
This research was conducted with the objective of studying the dynamics of soil temperature and water content as a function of the different amounts of black oat residue (Avena sativa Schreb.) in the soil cover, through ...
Testing road surface treatments to reduce erosion in forest roads in Honduras
(Pontificia Universidad Católica de Chile. Facultad de Agronomía e Ingeniería Forestal, 2009)
RWEQ wind erosion predictions for variable soil roughness conditions
(2016)
The soil surface is a main factor in all wind erosion prediction models including the Revised Wind Erosion Equation (RWEQ). The objetive of this study was to test the erodibility of two typical soils of the semiarid ...
A Note on Soil Moisture Memory and Interactions with Surface Climate for Different Vegetation Types in the La Plata Basin
(American Meteorological Society, 2015-04)
This work examines the evolution of soil moisture initialization biases and their effects on seasonal forecasts depending on the season and vegetation type for a regional model over the La Plata basin in South America. ...
The significance of root growth on cotton nutrition in an acidic low-P soil
(1999-01-01)
Toxic levels of Al and low availability of Ca have been shown to decrease root growth, which can also be affected by P availability. In the current experiment, initial plant growth and nutrition of cotton (Gossypium hirsutum ...

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 ...
