Microbial activity effect on aggregate stability after residue addition in a Mollisol and a Vertisol in the Pampas, Argentina
(Elsevier, 2020-12)Crop residue addition to the soil promotes an increase in microbial activity and, as a consequence, may improve soil aggregate stability. However, this effect may be different in soils with contrasting aggregation agents. ... -
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 ... -
Modelling inter-annual variation in dry matter yield and precipitation use efficiency of perennial pastures and annual forage crops sequences

Modelos alométricos de biomassa aérea para Prosopis affinis Spreng. em florestas nativas Espinal da Argentina = Modelos alométricos de biomassa aérea para Prosopis affinis Spreng. em florestas nativas Espinal da Argentina
(Departamento de Engenharia Agrícola, Universidade Federal de Campina Grande, 2019-06)Estimation of carbon stored in forest ecosystems requires accurate biomass prediction tools. The objective of this study was to determine the individual aerial biomass of Prosopis affinis and its distribution by component, ... -
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 ... -
Monitoreo de glifosato en agua superficial en Entre Ríos. La Investigación Acción Participativa como metodología de abordaje. Prácticas de mitigación de contaminación por escurrimiento.
(Ediciones INTA, 2017-12)Los agroquímicos representan potenciales fuentes de contaminación ambiental. Los ambientes acuáticos son sistemas vulnerables, receptores naturales de las sustancias emitidas por las actividades agrícolas e industriales ... -

(Estación Experimental Agropecuaria Paraná, INTA, 2021)El Módulo Demostrativo Ovino se instaló en el predio de la EEA Paraná con la finalidad de generar un sistema demostrativo de producción de carne ovina sobre campo natural con suplementación, factible de ser replicado por ... -
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 ... -
