(Wiley, 2021-01-11)Climate change and energy security promote using renewable sources of energy such as biofuels. High woody biomass production achieved from short-rotation intensive plantations is a strategy that is increasing in many parts ... -
Two decades of land cover mapping in the Rio de la Plata grassland region: The mapBiomas Pampa initiative
(Elsevier, 2022-09-08)The Río de la Plata Grasslands (RPG) region is the largest area of the temperate humid and subhumid grasslands biome in South America and one of the largest in the world. The region is located on fertile soils, generally ... -
Estudian la frecuencia histórica mensual de los incendios
(INTA, 2022-07-21)El Instituto de Clima y Agua del INTA, a través de su plataforma SEPA, pone a disposición una herramienta online que permite detectar los meses con mayor frecuencia de focos de calor, en las distintas regiones de la ... -
Que pasará con las lluvias en primavera y en verano.
(INTA, 2022-08-25)Los modelos internacionales anticipan que la probabilidad de que continue La Niña es de un 70 a un 80 % aproximadamente. Se trata del doble de la probabilidad calculada, según los datos históricos. Desde el Instituto de ... -
Cropland Net Ecosystem Exchange Estimation for the Inland Pampas (Argentina) Using EVI, Land Cover Maps, and Eddy Covariance Fluxes
(Frontiers Media, 2022-06-23)Estimations of Net Ecosystem Exchange (NEE) are crucial to assess the carbon sequestration/carbon source capacity of agricultural systems. Although several global models have been built to describe carbon flux patterns ... -
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 ... -
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 ... -
