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 ... -
Catabolic response and phospholipid fatty acid profiles as microbial tools to assess soil functioning
(2016-12)Microbial properties may help to provide an integrated view of changes in soil functioning associated with soil management or soil status. The fatty acid profiles of membrane phospholipids (PLFA) can give the composition ... -
Changes in soil phosphorus in different forest residue management
(INIA Uruguay y Facultad de Agronomía, Universidad de la República, 2012)We analyze the short term effect of the harvest residues management on the Phosphorus (P) fractions of the soil. Four trials were installed in Northeast Argentina on Vertisols (S1), Mollisols (S2) and Entisols (S3 and S4). ... -
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 ... -
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
(Asociación Argentina de la Ciencia del Suelo, 2013)Los cambios edáficos por el uso de la tierra no sólo surgen como consecuencia del sistema de implantación de cultivos, sino que también pueden influir la secuencia y rendimiento de las especies cultivadas. El objetivo del ... -
Efectos del fuego en la matriz del suelo : consecuencias sobre las propiedades físicas y mineralógicas
(2018-04)Los incendios constituyen disturbios de muy diverso origen y variadas implicancias. Además de los efectos sobre la vegetación, los incendios pueden afectar los componentes y las propiedades de los suelos. Las modificaciones ... -
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 ... -
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 ... -
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 ... -
Mapping the soils of an Argentine Pampas region using structural equation modeling
(2016-11)Current digital soil mapping (DSM) methods have limitations. For instance, it is difficult to predict a large number of soil properties simultaneously, while preserving the relationships between them. Another problem is ... -
Multivariate mapping of soil with structural equation modelling
(2017-09)In a previous study we introduced structural equation modelling (SEM) for digital soil mapping in the Argentine Pampas. An attractive property of SEM is that it incorporates pedological knowledge explicitly through a ... -
Relaciones geopedológicas y análisis multivariado de los atributos edáficos asociados a las dunas longitudinales del noroeste de la provincia de Buenos Aires, Argentina = Geopedological relations and multivariate analysis ofassociated edaphic attributes to the longitudinal dunes of the northwest of Buenos Aires province, Argentina
(Asociación Geológica Argentina, 2017)El enfoque geopedológico se refiere a las relaciones entre geomorfología y pedología, en tanto las características geomorfológicas del paisaje condicionan la intensidad de los procesos pedogenéticos y controlan numerosos ... -
Soil nitrous oxide emissions from Eucalyptus plantation in Argentina
(Elsevier, 2020-10-01)Nitrous oxide has a key effect on global climate development and 53% of N2O total annual emissions are related to fluxes from the soil. Land use and soil characteristics affect N2O emissions. There are not enough assessments ... -
Soil organic carbon, macro- and micronutrient changes in soil fractions with different lability in response to crop intensification
(Elsevier, 2018)Soils under no tillage have experienced unfavorable changes, mainly due to current agricultural practices that consist in monocultures that leave little residue cover. The inclusion of grass as cover crops during the winter ... -
