Monitoreo de glifosato en agua superficial en Entre Ríos. La investigación acción participativa como metodología de abordaje
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2017-08-01)Las pérdidas de glifosato desde agroecosistemas y su impacto sobre el agua superficial generan preocupación en los actores de la comunidad rural y urbana de Entre Ríos, habiéndose generalizado percepciones de riesgo. La ... -
Multi-level analysis of bird abundance and damage to crop fields
(Elsevier, 2014-12)Bird damage to agricultural crops is an important cause of economic loss for farmers worldwide. Predictive habitat models relating bird abundance and damage to characteristics of the agricultural environment at multiple ... -
Multiple-Herbicide resistance in a 2,4-D–Resistant waterhemp (Amaranthus tuberculatus) population from Nebraska
(Cambridge University Press; Weed Science Society of America, 2017-11)A 2,4-D-resistant tall waterhemp population (FS) from Nebraska was evaluated for resistance to other TIR1 auxin receptor herbicides and to herbicides having alternative mechanisms of action using greenhouse bioassays and ... -
Nestedness structure of bird assemblages in a fragmented forest in Central Argentina: the role of selective extinction and colonization processes
(BIOEXPLORA, 2021)Nestedness structure of bird assemblages in a fragmented forest in Central Argentina: the role of selective extinction and colonization processes. Nestedness analysis constitutes an important tool to understand the processes ... -
Nitrogen economy of early and late-sown maize crops
(Elsevier, 2018-11)Late sowing dates of maize are widely adopted in the Pampas region of Argentina, stabilising grain yields due to a more favourable water balance around flowering. However, late-sown crops are exposed to high soil N ... -
Nitrogen utilization efficiency in maize as affected by hybrid and N rate in late-sown crops
(2014-11)After the introduction of Bt-maize, late sowing is becoming an important strategy to stabilize yields in many areas of the Argentine Pampas. Increased nitrogen (N) availability and sharp reduction in radiation and temperature ... -
Nitrous oxide emission after the addition of organic residues on soil surface
(Elsevier, 2017)The addition of organic amendments with a low Carbon:Nitrogen (C:N) ratio to restore degraded soils may increase the emission of greenhouse gases and affect the storage of these elements in the topsoil. Our objectives were ... -
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 ... -
Nutrient dynamics in the Paraná River Delta: relationship to the hydrologic regime and the floodplain wetlands
(Elsevier, 2022-04)South America contains the most extensive freshwater wetlands in the world, associated with the floodplains of the Amazon, Orinoco and Paraná rivers. The Paraná River delta is a large wetland system strongly influenced by ... -
Occurrence patterns of the endangered Yellow Cardinal Gubernatrix cristata in north-east Argentina: only in savannahs and at sites away from roads
(BirdLife International, 2023)The endangered Yellow Cardinal Gubernatrix cristata is under pressure from habitat loss and from capturing for the cage bird trade. In north-east Argentina it is known to be associated with the Espinal ecoregion, but no ... -
Oportunidades para la cadena de maíz en Entre Ríos
(Facultad de Ciencias Económicas, Universidad Nacional de Entre Ríos, 2022-06)Entre Ríos representa una clara ilustración de la última expansión de frontera agrícola de la mano de la innovación tecnológica en la producción primaria, con implicancias en el sistema agroalimentario agroindustrial (SAA). ... -
Optimizing resource productivity in soybean-based sequences through long-term crop intensification
(Elsevier, 2023-10)Context: Cropping systems based on a single crop per year, such as soybean monoculture, result in an inefficient use of available resources and low productivity, and are usually related with a negative environmental impact. ... -
Oral acute toxicity of imidacloprid, thiamethoxam and clothianidin in eared doves: a contribution for the risk assessment of neonicotinoids in birds
