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 ... -
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 ... -
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 ... -
Soil moisture evaluation over the Argentine Pampas using models satellite estimations and in - situ measurements
(Elsevier, 2020-08-05)Study region: The Pampas region is located in the central-east part of Argentina, and is one of the most productive agricultural regions of the world under rainfed conditions. Study focus: This study aims at examining how ... -
Soybean frogeye leaf spot [Cercospora sojina] : first weather-based prediction models developed from weather station and satellite data
(2015-06-30)In Argentina, soybean frogeye leaf spot occurs sporadically. However, particularly in the Pampas Region, the incidence and severity of this fungal disease have significantly increased in the last years. In the present ... -
Spatially variable hidrologic impact and biomass production tradeoffs associated with Eucaliptus ( E. Grandis) cultivation for biofuel production in Entre Ríos, Argentina
(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 ... -
La teledetección como herramienta para la prevención, seguimiento y evaluación de incendios e inundaciones
(Asociación Española de Ecología Terrestre, 2008-09-11)Los incendios y las inundaciones son dos de los disturbios que más frecuentemente afectan a la población humana y a los recursos naturales. La teledetección, a través de sensores remotos activos y pasivos, constituye una ... -
The agro-ecological suitability of Atriplex nummularia and A. halimus for biomass production in Argentine saline drylands
(Springer, 2014-09)The choice of the best species to cultivate in semi-arid and arid climates is of fundamental importance, and is determined by many factors, including temperature and rainfall, soil type, water availability for irrigation ... -
The FLUXNET 20165 dataset and the ONEFlux processing pipeline for eddy covariance data
(Springer Nature, 2020-07-09)The FLUXNET2015 dataset provides ecosystem-scale data on CO2, water, and energy exchange between the biosphere and the atmosphere, and other meteorological and biological measurements, from 212 sites around the globe (over ... -
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 ... -
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) ... -
Tree invasion in secondary grasslands diminishes herbaceous biomass and diversity: A study of mechanisms behind the process
