Emisiones de gases de efecto invernadero en la producción ganadera
(Asociación Argentina para el Progreso de las Ciencias, 2018)Uno de los impactos ambientales provocados por el sector agropecuario es la emisión de gases de efecto invernadero (GEI). Los principales GEI emitidos desde el sector agropecuario son el dióxido de carbono (CO2), el ... -
Emisiones de óxido nitroso desde suelos agrícolas y alternativas para mitigarlas
(Asociación Argentina para el Progreso de las Ciencias, 2018)El óxido nitroso (N2O) es un gas efecto invernadero con un poder de calentamiento equivalente a 296 veces mayor que el del dióxido de carbono (CO2). El N2O es producido a partir del nitrógeno mineral que entra a los ... -
Eruption, transport mechanisms and deposition of Paleogene ignimbrites, southwestern North Patagonian Massif, Argentina
(Elsevier, 2023-11-01)The Paleocene-Eocene Catán Lil Ignimbrite (CLI) is one of the few occurrences within the explosive acid volcanism of this age in the extra-Andean region of the North Patagonian Massif. It represents a small-scale explosive ... -
Estimating Net Primary Productivity and Carbon Inputs by Soybean Crops in Argentina
(2017)Monitoring crop net primary productivity (NPP) and its proportion returned to soil in the form of carbon (C) input is vital to better understand the ecological responses to environmental and anthropogenic changes. However, ... -
Estudio de la aptitud de las tierras para uso agropecuario para la planificación de la urbanización en sectores rurales de la Región Metropolitana de Buenos Aires (RMBA)
(Universidad de Morón, 2020-03-04)La urbanización de tierras agrícolas se presenta en la actualidad como una problemática mundial, que instala al uso del suelo en el centro de la reflexión y debate sobre lo urbano. A fin de consensuar soluciones entre los ... -
Evaluación del crecimiento y estado nutricional de híbridos interespecíficos de Eucalyptus sometidos a estrés por anegamiento y salinidad = Evaluation of growth and nutritional status of interspecific hybrids of Eucalyptus subjected to waterlogging and salinity stress
(Asociación Argentina de la Ciencia del Suelo, 2016)Se realizó un experimento en condiciones controladas durante 90 días para estudiar la respuesta de dos combinaciones híbridas de Eucalyptus (Eucalyptus grandis x Eucalyptus camaldulensis y Eucalyptus grandis x Eucalyptus ... -
Evaluación y cartografía de la erosión eólica en la Argentina como base para la planificación de un uso sustentable
(Universidad de Morón, 2022-07-07)Los sistemas productivos de la República Argentina han registrado en los últimos años un cambio hacia una agricultura más intensiva, con mayores rendimientos unitarios y un desplazamiento de la frontera agrícola hacia zonas ... -
Evaluación y cartografía de la erosión hídrica en la Argentina
(Universidad de Morón, 2022-11-07)La intensificación agrícola y la expansión de la agricultura hacia ecosistemas de mayor fragilidad están produciendo un in cremento de los procesos de erosión hídrica de los suelos, ocasionando la disminución de su ... -
Extrapolation of a structural equation model for digital soil mapping
(Elsevier, 2020-05)In theory, two separate regions with the same soil-forming factors should develop similar soil conditions. This theoretical finding has been used in digital soil mapping (DSM) to extrapolate a model from one area to another, ... -
Fertilizer use soil health and agricultural sustainability
(MDPI, 2022-03-25)Due to the growing population and consequent pressure of use, agricultural soils must maintain adequate levels of quantity and quality to produce food, fiber, and energy, without falling victim to a negative impact on their ... -
From Kyoto to Paris: Measuring renewable energy policy regimes in Argentina, Brazil, Canada, Mexico and the United States
(2019-04)There are numerous strategies to lower greenhouse gas (GHG) emissions or to mitigate global climate change. One of them is to promote polices for developing renewable energy sources. There has been a growth in such policies ... -
Genesis of subtropical soils with stony horizons in NE Argentina: Autochthony and polygenesis
(Elsevier, 2009-03)Deep red soils, combining characteristics of highly weathered materials together with a significant degree of clay illuviation and with stony horizons close to the saprolite, are found in the Province of Misiones, northeastern ... -
Génesis de suelos en un sector del piedemonte aluvial del Chaco salteño
(2012-12)Se estudia la relación suelo-paisaje, las propiedades físico-químicas y la composición mineralógica de diferentes suelos dentro del cono aluvial del río Del Valle, en el borde occidental del Chaco salteño, en la provincia ... -
GH10 XynA is the main xylanase identified in the crude enzymatic extract of Paenibacillus sp. A59 when grown on xylan or lignocellulosic biomass
(2016)A novel bacterial isolate with polysaccharides degrading activity was identified as Paenibacillus sp., andnamed Paenibacillus sp. A59. Even though it is a strict mesophile, optimal xylanase activity of the crudeenzymatic ... -
Hierarchy of factors driving N2O emissions in non‐tilled soils under different crops
(Wiley, 2013-10)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 ... -
How to Improve Soil Anti-adhesion by Studying the Micro Relief of the Cuticle Surface of Digging Beetles: Exploring the Sulcophanaeus batesi Pronotum Using Translucent Replicas
(Oxford University Press, 2023-09-13)For some years, we have been studying the microtopography of soil diggers beetles fromArgentina to find the anti-adhesion pattern to decrease a soil particle adhesion for agricultural machinery components. In 2018, we ... -
Impact of cattle grazing on temperate coastal salt marsh soils
(Wiley, 2015-06)Over the last two decades, grazing intensity has increased in the temperate salt marshes of Samborombón Bay (Argentina) due to agricultural expansion and the displacement of domestic livestock to these areas. We investigated ... -
