Percepción del daño causado por aves en frutales y alternativas de manejo en el centro norte santafesino
(2018)Los cultivos de frutales pueden experimentar, entre otras adversidades, daños por aves. Mediante un censo a productores fruti-hortícolas en el centro norte de Santa Fe, evaluamos la percepción de daños causados por aves y ... -
Modelling long-term effects of cropping intensification reveals increased water and radiation productivity in the South-eastern Pampas
(Elsevier, 2013-08)Wheat/soybean double crop provides a reliable platform for cropping intensification in many subtropical and temperate areas, even in those with a short growing season as the South-eastern Pampas of Argentina. However, the ... -
Nitrógeno incubado en anaerobiosis y su relación con el nitrógeno orgánico en diferentes fracciones = Mineralizable nitrogen in anaerobiosis and its relationship with different organic n pools
(Asociación Argentina de la Ciencia del Suelo, 2014-07)Los diagnósticos de fertilidad nitrogenada usualmente utilizados no contemplan el aporte de la fracción orgánica del suelo. El nitrógeno (N) incubado en anaerobiosis (Nan), al igual que otras fracciones lábiles del N puede ... -
Spatio-Temporal Nitrogen Fertilizer Response in Maize: Field Study and Modeling Approach
(American Society of Agronomy, 2016)Maize (Zea mays L.) yield and its response to nitrogen (N) are affected by the spatial variability of the interaction between weather, management, and soil properties. The objectives of this study were (i) to evaluate the ... -
Stabilization of new carbon inputs rather than old carbon decomposition determines soil organic carbon shifts following woody or herbaceous vegetation transitions
(Springer, 2016-12)Background and aims: Although numerous studies have quantified the effects of land-use changes on soil organic carbon (SOC) stocks, few have examined simultaneously the weight of carbon (C) inputs vs. outputs in shaping ... -
Effects of fire disturbance on bird communities and species of mountain Serrano forest in central Argentina
(Taylor & Francis, 2014)In central Argentina, Serrano forest has a long history of fire disturbance; however, the impact of fire on avifauna remains unknown. We compared the avian–habitat relationships in forest patches with low, moderate, and ... -
Evaluation of Agricultural Production Systems Simulator as yield predictor of Panicum virgatum and Miscanthus x giganteus in several US environments
(Wiley, 2017)Simulation models for perennial energy crops such as switchgrass (Panicum virgatum L.) and Miscanthus (Miscanthus x giganteus) can be useful tools to design management strategies for biomass productivity improvement in ... -
