Comparison of field measurement methods of nitrous oxide soil emissions: from the chamber to the vial
(Sociedade Brasileira de Ciencia do Solo, 2020-07-16)Nitrous oxide (N2O) is a greenhouse gas that contributes substantially to global climate change. The N2O soil emissions have a large uncertainty because of its low atmospheric concentration levels and enormous spatial and ... -
Machine learning in space and time for modelling soil organic carbon change
(Wiley, 2020-05-20)Spatially resolved estimates of change in soil organic carbon (SOC) stocks are necessary for supporting national and international policies aimed at achieving land degradation neutrality and climate change mitigation. In ... -
Archeology, stone tools and RIMAPS technique A quantitive characterization of use - wear traces
(Microscopy Society of America, 2020-04-28)Archaeology relies on material remains to attain a broad comprehensive understanding of humanevolution, creating undeniable challenges to the methodological field. Microscopy and image techniques have had a paramount role ... -
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, ... -
Red Argentina de Ciencia y tecnología Forestal - REDFOR.ar. Un medio de articular y fortalecer las capacidades científico - Técnicas para el desarrollo forestal
(Facultad de Ciencias Forestales, Universidad Nacional de Santiago del Estero, 2019-12)La REDFOR.ar es una iniciativa conjunta de las instituciones vinculadas a las Ciencias Forestales, que está conformada por docentes, investigadores e instituciones relacionados con la educación, la ciencia y la tecnología ... -
Biotic and Abiotic Drivers of Topsoil Organic Carbon Concentration in Drylands Have Similar Effects at Regional and Global Scales
(Springer, 2019-11)Drylands contain 25% of the world’s soil organic carbon (SOC), which is controlled by many factors, both abiotic and biotic. Thus, understanding how these factors control SOC concentration can help to design more sustainable ... -
Soil stabilisation by water repellency under no-till management for soils with contrasting mineralogy and carbon quality
(Elsevier, 2019-08-23)No-till soil management is common around the globe, but the impacts on soil structural quality varies depending on cropping practice and inherent soil properties. This study explored water repellency as a driver of soil ... -
Sudangrass, an alternative lignocellulosic feedstock for bioenergy in Argentina
(Plos One, 2019-05)Sudangrass, Sorghum sudanense (Piper) Stapf, is a vigorous forage crop that has also been used for biogas, paper, and electricity production. Due to the large biomass yields achieved by sudangrass and the large area of ... -
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 ... -
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 ... -
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 ... -
Climate mediates the biodiversity–ecosystem stability relationship globally
(2018-08)The insurance hypothesis, stating that biodiversity can increase ecosystem stability, has received wide research and political attention. Recent experiments suggest that climate change can impact how plant diversity ... -
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 ... -
Potential Use of a poultry manure digestate as a Biofertiliser: evaluation of soil properties and Lactuca sativa growth
(2019-02)Anaerobic digestion is a process that is widely used for the treatment of organic wastes. The digestate can be used as a soil amendment or crop fertiliser. The aims of our work were to evaluate 1) the physicochemical ... -
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 gases de efecto invernadero desde el sector forestal
(Asociación Argentina para el Progreso de las Ciencias, 2018)Actualmente, una de las principales estrategias para la mitigación del cambio climático, se basa en el fomento de las prácticas de forestaciónreforestación debido al potencial que estos sistemas presentan para el secuestro ... -
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 ... -
Efecto de la secuencia de cultivos bajo siembra directa sobre la calidad de algunos suelos de la Región Pampeana = Effects of crop sequences under no-tillage on the quality of some soils of the Pampa Region
