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 ... -
Improving Latin American soil information database for digital soil mapping enhances its usability and scalability
(Copernicus Publications, 2022-09-14)Spatial soil databases can help model complex phenomena in which soils are decisive, for example, evaluating agricultural potential or estimating carbon storage capacity. The Soil Information System for Latin America and ... -
Including spatial correlation in structural equation modelling of soil properties
(Elsevier, 2018-06)Digital soil mapping techniques usually take an entirely data-driven approach and model soil properties individually and layer by layer, without consideration of interactions. In previous studies we implemented a structural ... -
Inclusion of Lotus tenuis in beef cattle systems in the Argentinian flooding pampa as an enteric methane mitigation strategy
(Taylor and Francis, 2024-04-01)While concerns about greenhouse gas (GHG) emissions and animal welfare persist, livestock farming offers unique ecosystem services. In Argentina, where livestock significantly contributes to GHG emissions, particularly ... -
The influence of soil properties on denitrifying bacterial communities and denitrification potential in no-till production farms under contrasting management in the Argentinean Pampas
(Elsevier, 2014-03)The aim of this work was to investigate the response of the structure, abundance and potential activity of denitrifiers to contrasting agricultural management in no-till production fields, across a regional scale within ... -
Interacción entre cultivos comerciales y de cobertura. Producción, dinámica del suelo y nitratos del agua
(Asociación Argentina de la Ciencia del Suelo, 2022-05-13)El agua y el nitrógeno (N) son los factores que generan las mayores limitaciones en la producción de ali mentos. El uso de los cultivos de cobertura (CC), modifica la dinámica del agua y N del suelo, por lo que es importante ... -
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 ... -
Manejo de bosques con ganadería integrada: impacto en las comunidades microbianas del suelo = forest management with integrated livestock: impact on soil microbial communities
(Asociación Argentina de la Ciencia del Suelo, 2016)El manejo de bosques polifíticos semicaducifolios en la Región Chaqueña que conservan la vegetación arbórea con ganadería integrada tiene como objetivo principal que las actividades ganaderas en zonas de bosques nativos ... -
Mapas de suelos afectados por sales en Argentina
(Red Argentina de Salinidad, 2022)Los suelos afectados por sales (SAS) se encuentran en todos los continentes y bajo casi todas las condiciones climáticas. Se trata de un grupo de suelos con muy diversas propiedades y cuyos rasgos en común son: i.- han ... -
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 ... -
La naturaleza, una brillante ingeniera en desarrollos tecnológicos
(Asociación Argentina para el Progreso de las Ciencias, 2022)La naturaleza nos brinda un sinfín de ideas para el desarrollo de nuevas tecnologías más sustentables y ecológicamente superiores. En el presente trabajo se describen, brevemente y con algunos ejemplos, los materiales ... -
Nitrification inhibitor addition to farm dairy effluent to reduce nitrous oxide emissions
(Sociedade Brasileira de Ciência do Solo, 2024-03)Increasing the use of nitrogen (N) fertilizers will be necessary to enhance grain and pasture yields to satisfy the growing world demand for food. Organic amendments, such as farm dairy effluents (FDE), are an alternative ... -
Nitrous oxide emission estimation from managed soils in Argentina: Differences between IPCC 2006 guidelines and the IPCC 2019 refinemet
(Facultad de Agronomía, Universidad de Buenos Aires, 2022-10-01)Based on the IPCC 2006 guidelines, the total GHG emission for 2016, in Argentina, were estimated to reach a total net 364 MtCO2eq. Particularly, N2O emissions from managed soils sector represented 12% of total emissions. ... -
Nitrous oxide emissions from a typical argiudol soil with organic and chemical amendments = Emisiones de óxido nitroso desde un suelo argiudol típico con enmiendas orgánicas y químicas
(Asociación Argentina de la Ciencia del Suelo, 2022-06-01)Diversification in fertilizer sources will be necessary to meet the growing demand for food worldwide. For this reason, organic amendments emerge as a synthetic fertilizers alternative. Composting organic waste stabilizes ... -
Números de curva de escurrimiento determinados para una microcuenca aforada con suelos argiudoles de permeabilidad moderada
(Asociación Argentina de la Ciencia del Suelo, 2022-07-01)El escurrimiento asociado a la erosión hídrica determina a menudo un costo ambiental debido a la pérdida de agua, suelo, nutrientes y materia orgánica de las tierras agrícolas, así como el transporte de contami nantes hacia ... -
Organic carbon stored in soils under different land uses and soil textures in southeast Argentinean Mesopotamia
(2021-08-25)Soil use affects soil organic carbon (OC) stocks by regulating the quantity and quality of incorporated organic matter. Understanding how soil texture and other factors control OC concentration and accumulation would be ... -
