Ammonia emissions from the agriculture sector in Argentina; 2000–2012
(Elsevier, 2018-04)Agriculture is one of the key economic sectors in Argentina and, in the last decades, the increase in prices and competitiveness of some grains has imposed important changes. In this process, crop cultivation occupied ... -
An insight into the patterns and controls of the structure of South American Chaco woodlands
(Wiley, 2022)Logging, grazing, wood extraction, and anthropogenic fires are pervasive throughout the subtropical dry vegetation of South America leading to changes in woodlands structure and ultimately its degradation. The Chac ohaco ... -
Analysis of biophysical variables in an onion crop (Allium cepa L.) with nitrogen fertilization by sentinel-2 observations
(MDPI, 2022-08-11)The production of onions bulbs (Allium cepa L.) requires a high amount of nitrogen. Ac cording to the demand of sustainable agriculture, the information-development and communication technologies allow for improving the ... -
Analysis of preharvest meteorological conditions in relation to concentration of fumonisins in kernels of two genetically different maize hybrids
(Springer, 2020-09-25)The effects of meteorological conditions around silking (Si) and physiological maturity (PM) on production of fumonisins (FB=FB1 + FB2) in maize kernels were analyzed. Kernel FB contents were determined on kernel samples ... -

Apropiación humana de la producción primaria en el Chaco Seco
(Asociación Argentina de Ecología, 2013-04)El Chaco Seco experimenta altas tasas de deforestación y transformación productiva. Estimamos la magnitud de la apropiación humana de la productividad primaria neta (PPN) aérea de esta región por vías directas (producción ... -
Are remote sensing evapotranspiration models reliable across South American ecoregions?
(Wiley, 2021-11-01)Many remote sensing-based evapotranspiration (RSBET) algorithms have been proposed in the past decades and evaluated using flux tower data, mainly over North America and Europe. Model evaluation across South America has ... -
Arsenic and fluoride in water in northwestern Buenos Aires : their association with natural landscape elements
(2017-02)Numerous publications analyze the origin of Arsenic and Fluoride, their behavior and distribution in groundwater indicating the importance in understanding the relation between their occurrence with other physical and ... -
Assessment of multi - date sentinel - 1 polarizations and GLCM texture features capacity for onion and sunflower classification in an irrigated valley: An object level approach
(MDPI, 2020-06-13)The objective of this work is to evaluate the capacity of the C-band Synthetic Aperture Radar (SAR) time series imagery, acquired by the European satellite Sentinel-1 (S1), for the agriculture crop classification and its ... -
Assessment of the soil water content in the Pampas region using SWAT
(2016-02)La región Pampeana ha experimentado recientemente una expansión de la agricultura hacia ambientes más frágiles, que se ha asociado con un aumento en la frecuencia de las sequías que afectan a toda la región. En el presente ... -
Attribution of carbon dioxide fluxes to crop types in a heterogeneous agricultural landscape of Argentina
(Springer, 2014-10)The increasing proportion of agricultural lands worldwide makes it necessary to intensify the research concerning the carbon exchange at agricultural sites. In order to determine the Net Ecosystem Exchange (NEE) in an ... -
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 ... -
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 ... -
Carbon and water vapor balance in a subtropical pine plantation
(2016-10)Afforestation has been proposed as an effective tool for protecting primary and/or secondary forests and for mitigating atmospheric CO2. However, the dynamics of primary productivity differs between plantations and natural ... -
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 ... -

(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2012-08)El delta del río Paraná es un ecosistema de alta fragilidad ambiental y muy susceptible a las inundaciones. A su vez, se caracteriza por tener una importante actividad económica, social y productiva. Disponer de una ... -
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 ... -
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 ... -
