Determinantes hidrológicos y edáficos de la dinámica de algunos contaminantes en una microcuenca de Pampa Ondulada bajo siembra directa
(Facultad de Agronomía, Universidad de Buenos Aires, 2020-03-19)En la Región Pampeana se observan procesos de degradación física y de erosión hídrica aún en planteos de siembra directa. Para la evaluación de estos procesos se trabajó de manera conjunta a nivel de microcuenca, lote/parche ... -
Pesticide dynamics in agroecosystems: Assessing climatic and hydro-physical effects in a soybean cycle under no-tillage
(Elsevier, 2022-09)The high rate of No-Tillage (NT) adoption in Argentina has been followed by conspicuous application of herbicides due to RR crops selection and recently due to weed resistance. In addition, no-tillage in the Rolling Pampa ... -
Soil structure and glyphosate fate under no-till management in the Pampa region. I. Soil structural anisotropy and hydro-physical behavior
(Elsevier, 2022-05-03)Several studies have reported a frequent occurrence of platy structures in soils under no tillage (NT), mostly in silty ones. The objective of this study was to evaluate the morphological features and the pore architecture ... -
Soil structure and glyphosate fate under no-till manangement in the pampa region. II. Glyphosate and AMPA persistence and spatial distribution in the long-term. A conceptual model
(Elsevier, 2022-07-14)Glyphosate and AMPA were measured in a no-tilled (NT) soil and in the runoff resulting from the rain simulation carried out after 270 days of the application of the herbicide. Glyphosate concentration was in low values in ... -
Toxicities of glyphosate- and cypermethrin-based pesticides are antagonic in the tenspotted livebearer fish (Cnesterodon decemmaculatus)
(2016)Although pesticide contamination of surface waters normally occurs in the form of mixtures, the toxicity and interactions displayed by such mixtures have been little characterized until now. The present study examined ...
