Revisiting sampling duration to estimate N2O emission factors for manure application and cattle excreta deposition for the UK and Ireland
(Elsevier, 2022-08-29)According to the available guidelines, good practices for calculating nitrous oxide (N2O) emission factors (EFs) for livestock excreta and manure application include that sampling duration should be of at least one year ... -
Como planificar la siembra de trigo ante un escenario hídrico heterogéneo
(INTA, 2022-05-11)En un contexto general de déficit hídrico y la posibilidad de un invierno seco, especialistas del INTA detallan cómo se encuentran las zonas trigueras, de acuerdo a las últimas lluvias. Entre las recomendaciones ponen el ... -
Riparian buffer strips influence nitrogen losses as nitrous oxide and leached N from upslope permanent pasture
(Elsevier, 2022-05-23)Riparian buffer strips can have a significant role in reducing nitrogen (N) transfers from agricultural land to freshwater primarily via denitrification and plant uptake processes, but an unintended trade-off can be elevated ... -
Characterization of the annual regime of surface solar irradiance over Argentine Pampean Region using GL 1.2 satellite-based data
(Elsevier, 2022-05-12)Detailed description of the solar resource (spatial distribution and temporal variations) is highly desirable in the context of climate monitoring, agricultural planning and energy technologies; however, one shortcoming ... -
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 ... -
Effects of fertilizer type on nitrous oxide emission and ammonia volatilization in wheat and maize crops
(Wiley, 2022-01-28)About half of the applied nitrogen (N) is not consumed by crops, causing environmental and economic costs. This N can be lost as ammonia (NH3) volatilization, nitrous oxide (N2O) emission or leaching, among others. This ... -
Detección de outliers en muestras de entrenamiento generadas mediante interpretación visual
(Sociedad Argentina de Informática, 2021-10-18)Las clasificaciones supervisadas son procesos extremadamente sensibles a la calidad de las muestras utilizadas. La presencia de outliers en las muestras de entrenamiento suele ser una fuente de error muy frecuente. El ... -
Plataforma de datos de granizo de Argentina
(Sociedad Argentina de Informática, 2021-10-18)El granizo es un fenómeno que afecta fuertemente al sector agropecuario con posibles pérdidas económicas importantes y daños considerables en los cultivos[1]. Por ende, la realización de análisis temporales y espaciales e ... -
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 ... -
Forest strips increase connectivity and modify forests functioning in a deforestation hotspot
(Elsevier, 2021-04-28)Land use changes are occurring with unprecedented magnitude and intensity, imposing global impacts on ecosystem services (ES) and biodiversity. While the impacts of land use changes are increasingly recognized, understanding ... -
Differential sensitivities of electricity consumption to global warming across regions of Argentina
(Springer, 2021-05-27)The description of the relationship between temperature (T) and electricity consumption (EC) is key to improving our understanding of a potential climate change amplification feedback and, thus, energy planning. We sought ... -
Which pixel is a forest? Tree crown delineation using VHR images to estimate tree cover in landsat based classification
(IEEE Geoscience and Remote Sensing Society, 2021-07-12)Determining the percentage of tree crown cover is extremely important to establish in advance which forest types can be classified with high resolution sensors such as Landsat. This paper describes the determination of a ... -
