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 ... -
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 ... -
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 ... -
Variabilidad climática y expresión de la fusariosis de la espiga de trigo en la región pampeana
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2015-12)En Argentina, la fusariosis de la espiga de trigo (FET) es predominantemente causada por el hongo Fusarium graminearum. La naturaleza esporádica de la FET asociada a factores meteorológicos estimuló el desarrollo de modelos ... -
Regional isoprenoid emission from Eucalyptus grandis forests in northeastern Argentina
(2016)Eucalyptus species are strong source of isoprenoid emission. The objective of the present study was to estimate isoprenoid emissions from Eucalyptus grandis forest crops in the Entre Rios province in the Mesopotamia region ... -
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) ... -
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 ... -
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 ... -
Validación de sistemas de pronóstico del impacto de la fusariosis de la espiga en cultivares de trigo
(2016-07)En Argentina, el principal agente causal de la enfermedad conocida como fusariosis de la espiga de trigo (FET) es el hongo Fusarium graminearum (Schwabe) (teleomorfo Gibberella zeae (Schwein)). La FET es una enfermedad ... -
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 ... -
National-scale soybean mapping and area estimation in the United States using medium resolution satellite imagery and field survey
(2017)Reliable and timely information on agricultural production is essential for ensuring world food security. Freely available medium-resolution satellite data (e.g. Landsat, Sentinel) offer the possibility of improved global ... -
Propuesta de sistematización agrohidrológica en cuencas de llanura con énfasis predial y consorciado = Proposal for agro-hydrological systematization in basins plaines with emphasis predial and consortial
(Universidad Nacional del Litoral. Facultad de Ciencias Agrarias, 2017)Existe escasa tecnología para el manejo de aguas superfi ciales en áreas de planicie extrema e inundable, aumentada por la controversia de opinión en cuanto al modo de encarar la solución de los excesos y défi cit hídricos. ... -
Selecting control sites for post-fire ecological studies using biological criteria and MODIS time series data
(Association for Fire Ecology, 2017)Wildland fires play a key role in the functioning and structure of vegetation. The availability of sensors aboard satellites, such as Moderate Resolution Imaging Spectroradiometer (MODIS), makes possible the construction ... -
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 ... -
A multi-resolution approach to national-scale cultivated area estimation of soybean
(2017-06)Satellite remote sensing data can provide timely, accurate, and objective information on cultivated area by crop type and, in turn, facilitate accurate estimates of crop production. Here, we present a generic multi-resolution ... -
CO2 and N2O flux balance on soybean fields during growth and fallow periods in the Argentine Pampas—A study case
(Elsevier, 2017-06)The estimation of the GHG balance of agroecosystems is essential to evaluate the impact of agriculture on the composition of the atmosphere. Cultivated soils may act as a sink or a source of CO2 and usually emit N2O. The ... -
Development of agroclimatic zoning model to delimit the potential growing areas for macaw palm (Acrocomia aculeata)
