(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2011-04)La información meteorológica resulta de gran utilidad en distintas disciplinas como la agronomía y la hidrología, entre otras. La observación de variables y fenómenos meteorológicos se lleva a cabo en Estaciones Meteorológicas ... -
Weather-based predictive models for Diaporthe helianthi ascospore release in Uruguay
(Springer, 2019-08-01)Stem canker (SC), caused by Diaporthe helianthi, is the most serious sunflower disease in Uruguay. Yield losses have been estimated up to 75%. Chemical control is one of the strategies used to manage this disease, but ... -
Building a Data Set over 12 Globally Distributed Sites to Support the Development of Agriculture Monitoring Applications with Sentinel-2
(MDPI, 2015-12)Developing better agricultural monitoring capabilities based on Earth Observation data is critical for strengthening food production information and market transparency. The Sentinel-2 mission has the optimal capacity for ... -
Changes in vegetation seasonality and livestock stocking rate in La Pampa Province (Argentina) = Cambios en la estacionalidad de la vegetación y la carga animal en la provincia de La Pampa (Argentina)
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2019)Crop production is traversing expansion and intensification processes all over the planet and in consequence the large scale cattle production is being displaced to marginal lands with lower stocking capacity. The objective ... -
A land cover map of Latin America and the Caribbean in the framework of the SERENA project
(Elsevier, 2013-05-15)Land cover maps at different resolutions and mapping extents contribute to modeling and support decision making processes. Because land cover affects and is affected by climate change, it is listed among the 13 terrestrial ... -
Carbon dioxide fluxes on a soybean field in Argentina: influence of crop growth stages
(Bentham Open, 2010)CO2 fluxes were measured in a soybean field in the Province of Buenos Aires, Argentina, with an eddy covariance system consisting of a CO2/H2O infrared gas analyzer and a sonic anemometer. The measurements were carried out ... -
Climate change in Argentina: trends, projections, impacts and adaptation
(Wiley, 2015)In most of Argentina, the warming since 1901 was a little lower than the global average, although with strong trends in temperature extremes and in heat waves during the most recent decades. There was a remarkable increase ... -
Changes in evapotranspiration and phenology as consequences of shrub removal in dry forests of central Argentina
(Wiley, 2015-10)More than half of the dry woodlands (forests and shrublands) of the world are in South America, mainly in Brazil and Argentina, where in the last years intense land use changes have occurred. This study evaluated how the ... -
Total and aboveground radiation use efficiency in C3 and C4 grass species influenced by nitrogen and water availability
(Wiley; Japanese Society of Grassland Science, 2015-09)Absorbed solar radiation and radiation use efficiency (RUE) can be used to estimate net primary productivity of terrestrial ecosystems. In ecosystems dominated by grasses, belowground productivity cannot be neglected in ... -
Agrohydrological analysis of groundwater recharge and land use changes in the Pampas of Argentina
(Elsevier, 2019-03)This paper studies the changes of groundwater, climate and land use in the Pampas of Argentina. These changes offer opportunities and threats. Lowering groundwater without irrigation causes drought and successive crop and ... -
Ajuste de modelos logísticos a la tasa de incremento de severidad de manchas foliares ocasionadas por Alternaria tenuissima en arándano = Logistic models adjustment to growth rate of severity of blueberry leaf spot caused by Alternaria tenuissima
(Asociación Argentina de Horticultura, 2014)La severidad de manchas foliares, ocasionadas por Alternaria tenuissima en arándano, fue observada en el cultivar O’Neal en San Pedro (59º 38’ S; 33º 44’ O), Concordia (31º 19’ S; 58º 5’ O) y Gualeguaychú (33º 01’ S; ... -
Barriers and solutions to conducting large international, interdisciplinary research projects
(Springer, 2017-12)Global environmental problems such as climate change are not bounded by national borders or scientific disciplines, and therefore require international, interdisciplinary teamwork to develop understandings of their causes ... -
Multi-Temporal analysis of remotely sensed information using wavelets
(Scientific Research Publishing, 2012)Land cover changes (LCC) are an important component of Global Change. LCC can be described not only by its occur-rence, but also by the land cover replacement, causal agent and change duration or recuperation. Nowadays, ... -
Towards a set of agrosystem-specific cropland mapping methods to address the global cropland diversity
(Informa UK Limited, 2016)Accurate cropland information is of paramount importance for crop monitoring. This study compares five existing cropland mapping methodologies over five contrasting Joint Experiment for Crop Assessment and Monitoring (JECAM) ... -
Impact of land use during winter on the balance of greenhouse gases
(Wiley, 2018)The increase in atmospheric greenhouse gases (GHGs) can be mitigated by capturing CO2 from the atmosphere and/or by reducing their emissions. Replacing winter intercrop fallow by cover crops (CCs) can sequester carbon and ... -
Has climate change opened new opportunities for wheat cropping in Argentina?
(Springer, 2013-03)As a result of climate change, and in particular rainfall changes, agricultural production is likely to change across the globe. Until now most research has focused on areas which will become unsustainable for agricultural ... -
Relationship between biophysical parameters and synthetic indices derived from hyperspectral field data in a coastal marsh from Buenos Aires Province, Argentina
(Springer, 2016-02)Remote sensing tools allow the environmental evaluation of coastal wetlands at a landscape scale, but a deeper understanding is needed of the interactions between biophysical parameters and the electromagnetic signal. The ... -
Attribution of carbon dioxide fluxes to crop types in a heterogeneous agricultural landscape of Argentina
