Agricultural loess soils along a climosequence evidenced different susceptibility to acidification by simulated N-fertilization
Iturri, Laura Antonela; Buschiazzo, Daniel Eduardo (Elsevier, 2018)Agricultural loess soils of the central region of Argentina show acidification evidences linked to both climatic conditions and N-fertilization. Because of that, simulations to estimate the future acidification trends ... -
El agua. De la molécula a la bioesfera
Adamoli, Jorge; Aimar, Silvia Beatriz; Buschiazzo, Daniel Eduardo; Cavagnaro, Juan Bruno; Ginzburg, Ruben; Jonas, Olga; Quiroga, Alberto Raul; Rabotnikof, Celia Monica; Seiler, Roberto; Strizler, Nestor Pedro; Taleisnik, Edith; Vinocur, Marta Graciela (Ediciones INTA, 2008-02)Este libro propone realizar un "tour d´horizon"de la biología utilizando el agua como lazo de unión, analizando los diferentes procesos donde participa y relacionándola con las estructuras de la vida. -
Comparing adjacent cultivated and “virgin” soils in wind erosion affected environments can lead to errors in measuring soil degradation
Iturri, Laura Antonela; Avecilla, Fernando; Hevia, Graciela Gloria; Buschiazzo, Daniel Eduardo (Elsevier, 2016-02)Soil degradation has been frequently evaluated by comparing cultivated soils with paired reference pedons. Evaluated were some physical and chemical properties of cultivated and reference soils of a semiarid environment ... -
Control de la erosión eólica con un estabilizador artificial en un torripsammente ustico = Wind erosion control with an artificial stabilizer in an ustic torripsamment
Avecilla, Fernando; Ramirez Haberkon, Nancy Belén; Aimar, Silvia Beatriz; Buschiazzo, Daniel Eduardo (Asociación Argentina de la Ciencia del Suelo, 2016-12)La erosión eólica es uno de los principales procesos de degradación de suelos de ambientes áridos y semiáridos. Una alternativa de control de este proceso es la estabilización del suelo por medio de fijadores artificiales. ... -
Dynamics of volcanic ash remobilisation by wind through the Patagonian steppe after the eruption of Cordón Caulle, 2011
Panebianco, Juan Esteban; Mendez, Mariano Javier; Buschiazzo, Daniel Eduardo; Bran, Donaldo Eduardo; Gaitan, Juan Jose (2017)Wind erosion of freshly-deposited volcanic ash causes persistent storms, strongly affecting ecosystems and human activity. Wind erosion of the volcanic ash was measured up to 17 months after the ash deposition, at 7 sites ... -
Effect of temporal resolution of wind data on wind erosion prediction with the Revised Wind Erosion Equation (RWEQ) = Efecto de la resolución temporal de los datos de viento en la predicción de la erosión eólica con el modelo RWEQ
Panebianco, Juan Esteban; Buschiazzo, Daniel Eduardo (Asociación Argentina de la Ciencia del Suelo, 2013-12)In wind erosion modelling and assessment, wind speed is a crucial variable. Available records for large regions of the world generally show relatively low temporal resolution. The effect of using wind data of different ... -
Effects of low-scale landscape structures on aeolian transport processes on arable land
Siegmund, Nicole; Funk, Roger; Koszinsky, Sylvia; Buschiazzo, Daniel Eduardo; Sommer, Michael (Elsevier, 2018-06)The landscape of the semiarid Pampa in central Argentina is characterized by late Pleistocene aeolian deposits, covering large plains with sporadic dune structures. Since the current land use changed from extensive livestock ... -
Efficiency of Big Spring Number Eight (BSNE) and Modified Wilson and Cook (MWAC) samplers to collect PM10, PM2.5 and PM1
Mendez, Mariano Javier; Funk, Roger; Buschiazzo, Daniel Eduardo (Elsevier, 2016-06)The internal efficiency of Big Spring Number Eight (BSNE) and Modified Wilson and Cook (MWAC) samplers for trapping PM10, PM2.5 and PM1 were tested in a wind tunnel, at two wind speeds (3.0 and 6.8 m s 1) in the saltation ... -
Flujos de carbono y nitrógeno bajo distintos sistemas de labranza en la región semiárida pampeana
Bono, Angel Alfredo (Facultad de Agronomía, Universidad de Buenos Aires, 2010-03)Los contenidos de carbono y nitrógeno orgánicos del suelo están relacionados con su capacidad productiva. Esta relación es esperable que sea más estrecha en suelos de zonas áridas y semiáridas. La cantidad de carbono que ... -
Light acidification in N-fertilized loess soils along a climosequence affected chemical and mineralogical properties in the short-term
Iturri, Laura Antonela; Buschiazzo, Daniel Eduardo (Elsevier, 2016-04)Some evidences indicate that N-fertilization of crops decreased pH values of loess soils of the Argentinean Pampas in the last decades. We analyzed the A-horizons of four N-fertilized (F) and non-fertilized (NF) paired ... -
Meteorological conditions during dust (PM10) emission from a tilled loam soil: Identifying variables and thresholds
Avecilla, Fernando; Panebianco, Juan Esteban; Buschiazzo, Daniel Eduardo (Elsevier, 2017-10-15)Soil wind erosion and consequent PM10 emission is a complex process that has been related to surface properties and meteorological conditions. Most of the studies have emphasized on the relationship between the surface ... -
PM10 emission efficiency for agricultural soils: Comparing a wind tunnel, a dust generator, and the open-air plot
Avecilla, Fernando; Panebianco, Juan Esteban; Méndez, Mariano Javier; Buschiazzo, Daniel Eduardo (Elsevier, 2018)The PM10 emission efficiency of soils has been determined through different methods. Although these methods imply important physical differences, their outputs have never been compared. In the present study the PM10 emission ... -
PM10 emission, sandblasting efficiency and vertical entrainment during successive wind-erosion events: a wind-tunnel approach
Panebianco, Juan Esteban; Mendez, Mariano Javier; Buschiazzo, Daniel Eduardo (Springer, 2016-11)A wind-tunnel experiment was carried out to measure saltation and PM10 (particulate matter with a mean aerodynamic diameter less than 10 μ μ m) emission during three successive wind-erosion events on three different ... -
