Increased cropping intensity improves crop residue inputs to the soil and aggregate-associated soil organic carbon stocks
(Elsevier, 2017-01)Many South American agroecosystems are based mainly on soybean [Glycine max (L.) Merr.] as a sole crop in the year, which has increased concerns regarding soil conservation and ecosystems sustainability. The increase in ... -
Evaluation of soil degradation produced by rice crop systems in a Vertisol, using a soil quality index
(2017-03)One of the priorities of land planners is the development of methodologies that allow the detection of negative impacts on soils. The objective of this work was to evaluate the impact of rice production systems that use ... -
Efecto del fuego o el corte sobre la producción y la calidad forrajera de un pajonal dominado por Panicum prionitis = Effect of fire or mowing on the forage supply and quality of a Panicum prionitis tall grassland
(Asociación Argentina de Producción Animal, 2017-06)El aumento de superficie destinada a la agricultura ha provocado el desplazamiento de la ganadería hacia ambientes tradicionalmente clasificados como “marginales”. Este es el caso de islas y campos bajos del valle de ... -
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 ... -
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 ... -
Developments in the “profil cultural” method for an improved assessment of soil structure under no-till
(Elsevier, 2017-11)In France, agronomists have studied the effects of cropping systems on soil structure using a field method that is based on a visual description of the soil structure. This “profil cultural” method was designed as a field ... -
Modelling inter-annual variation in dry matter yield and precipitation use efficiency of perennial pastures and annual forage crops sequences
(2018)In livestock systems of the Argentinean Pampas, its forage production stability relies on the integration of two landcovers, annual forage crop sequences and perennial pastures. Despite the key role that these forage ... -
Modelling stover and grain yields, and subsurface artificial drainagefrom long-term corn rotations using APSIM
(2018)The Agricultural Production Systems Simulator (APSIM) is a key tool to identify agricultural managementpractices seeking to simultaneously optimize agronomic productivity and input use efficiencies. The aimsof this study ... -
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 ... -
Patch and landscape responses of bird abundance to fragmentation in agroecosystems of east-central Argentina = Abondance d'oiseaux dans les îlots et les paysages à la suite de la fragmentation dans des agrosystèmes du centre-est de l'Argentine
(Society of Canadian Ornithologists and Bird Studies Canada, 2018)Forest fragmentation in agroecosystems is linked to declines of avian species worldwide. Agriculture has greatly reduced native forest cover in east-central Argentina. Assessing the influence of fragmentation on forest ... -
Avifaunal inventory of northern Entre Ríos, Argentina: noteworthy records and conservation prospects
(Museo Argentino de Ciencias Naturales Bernardino Rivadavia, 2018)Biodiversity inventories remain fundamental tools for biodiversity conservation. Neotropical biota has poor faunal inventories. In Argentina, the avifauna of the province of Entre Ríos is still not well known. Here, we ... -
Modelling forage yield and water productivity of continuous crop sequences in the Argentinian Pampas
(Elsevier, 2018-01)In recent years, the use of forage crop sequences (FCS) has been increased as a main component into the animal rations of the Argentinian pasture-based livestock systems. However, it is unclear how year-by-year rainfall ... -
Contribution of honeybees to soybean yield
(Springer, 2018-02)Despite the economic importance of soybean [Glycine max (L.) Merr.], knowledge on the contribution of entomological pollination on seed yield is scarce. This study estimates the production of soybean resulting from pollination ... -
Vertical distribution of root biomass and soil carbon stocks in forage cropping systems
(Springer, 2018-02)Background and aims: Forage cropping systems may differentially affect the vertical distribution of roots and soil organic C stock (C-OM). In annual crops sequences (ACS) and perennial pastures (PP), we assessed the ... -
Limitantes nutricionales y variabilidad espacio-temporal del rendimiento en colza
(2018-04)La información agronómica desarrollada para el cultivo de colza es aún escasa en Argentina. Analizar el efecto de las limitantes nutricionales y de propiedades físicas sobre la variación espacial del rendimiento de colza ... -
Fitotoxicidad de un formulado comercial de glifosato sobre Lemna gibba L.
