(Asociación Española de Ecología Terrestre (AEET), 2021-08-23)La variación temporal del índice NDVI predice los cambios temporales de la cobertura vegetal en las tierras secas de la Patagonia argentina. En las tierras secas, la vegetación natural es una fuente importante de sustento ... -
Soil compaction alleviation by deep non - inversion tillage and crop yield responses in no tilled soils of the Pampas Region of Argentina. A meta - analysis
(Elsevier, 2021-05-03)No till is considered part of the good management practices recommended in conservation agriculture. Regardless of the benefits of this practice, shallow compaction or soil hardening by farm machinery traffic can lead to ... -
Pores size distribution and pores volume density of mollisols and vertisols under different cropping intensity managements with no - tillage
(Elsevier, 2021-09-15)In the Argentina Pampas, one of the most extensive agricultural areas in the temperate fringe of southern hemisphere, soil health is jeopardized mostly by the decline of physical and biological properties due to soil ... -
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 ... -
Bot-graphy: An original technique for plant anatomy study based o metallography
(Cambridge University Press, 2021-07-30)Plant anatomists are recurrently looking for safer and faster methods to improve the observations of plants tissues, searching for images with better resolution. Nevertheless, some plant materials are difficult to handle ... -
Do soil carbon sequestration and soil fertility increase by including a gramineous cover crop in continuous soybean?
(Wiley, 2021-04-08)Cover cropping is a farming practice that may improve C sequestration and soil fertility, but these effects can vary under different edaphoclimatic conditions. The effects of including a winter gramineous cover crop (CC) ... -
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). ... -
Rendimiento del maíz ante el agregado de zeolita y yeso a la fertilización nitrogenada en un Argiudol típico de San Antonio de Areco
(Ediciones INTA, 2021-04)Los objetivos del presente trabajo fueron evaluar los efectos de la aplicación de yeso y zeolitas acompañando la fertilización nitrogenada sobre el rendimiento del cultivo de maíz y estimar los costos en relación con el ... -
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 ... -
