Modeling added spatial variability due to soil improvement: Coupling FEM with binary random fields for seismic risk analysis
(Elsevier LtdUniversidad EAFIT. Departamento de Ingeniería Mecánica, 2018-01-01)
A binary mixture homogenization model is proposed for predicting the effects on liquefaction-induced settlement after soil improvement based on the consideration of the added spatial variability between the natural and the ...
Soil as a capacitor: Considering soil water content improves temporal models of productivity
(Academic Press Ltd - Elsevier Science Ltd, 2013-11)
Above-ground net primary production (ANPP) in arid and semiarid ecosystems is mainly explained by precipitation (ppt). However, when this relationship is evaluated taking into consideration data from different years in the ...
Restoration of productivity in tropical eroded soils under appropriate managementRestauración de la productividad a los suelos tropicales erosionados atendiéndolos adecuadamente

Improving the efficiency in the detection of gamma activities in environmental soil samples: influence of the granulometry and soil density
(Springer, 2019-07)
In this work the efficiency calibration curves for a HPGe gamma detector were obtained from soil standards prepared in our laboratory using typical Argentine regional soils. They were made in pot and Petri dish geometries, ...
Combining cover crops and low nitrogen fertilization improves soil supporting functions
(2019-07)
Background and aims: Cover crops may restore soil functions lost with single summer crop sequences enhancing soil organic carbon and nitrogen (SOC and SON) stocks. We investigated the effect of cover crops and low nitrogen ...
Changes of paradigms in agriculture soil microbiology and new challenges in microbial ecology
(Gauthier-Villars/Editions Elsevier, 2019-02)
At the beginning of the 20th century Louis Pasteur laid the foundations of classical microbiology, based on the cultivation of microorganisms. Microbiology ceased to be an exclusive concern in matters of health or food ...
Effects of organic mulch on soil fertility: a comparison study using leafy biomass from tree species
(Universidade Federal de Mato Grosso, 2020)
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) ...
Developments in the “profil cultural” method for an improved assessment of soil structure under no-till
(Elsevier, 2017-11)
In France, agronomists have studied the effects of cropping systems on soil structure using a field method that is based on a visual description of the soil structure. This “profil cultural” method was designed as a field ...
Mejora de propiedades físicas por el uso de especies megatérmicas en un suelo sódico templado
(2015-06)
Las especies megatérmicas pueden disminuir el pH del suelo y los niveles de sodicidad cuando se implantan en suelos sódicos, pero poco se sabe acerca de su capacidad para mejorar la condición física de suelos sódicos ...
