(Asociación Argentina de Agrometeorología, 2022-09-28)Entre los diversos condicionamientos con los que cuenta la producción agropecuaria, las adversidades climáticas y entre ellas las heladas, revisten gran interés a causa de las pérdidas en la producción que generan. En ... -
Manejo de Llamas extra-andinas. Observaciones que contribuyen a su bienestar en un contexto no originario
(Asociación Argentina de Producción Animal, 2013-12)El uso de camélidos sudamericanos (CSA) se remonta a 12000 años atrás, cuando los primeras poblaciones humanas comenzaron a cazar guanacos (Lama guanicoe) y vicuñas (Vicugna vicugna), CSA silvestres, para alimentarse. ... -
Mapping the soils of an Argentine Pampas region using structural equation modeling
(2016-11)Current digital soil mapping (DSM) methods have limitations. For instance, it is difficult to predict a large number of soil properties simultaneously, while preserving the relationships between them. Another problem is ... -
El material parental de los suelos de la Región Pampeana en base a la mineralogía de arenas. Aplicaciones a la interpretación de procesos pedológicos
(Asociación Argentina de Ciencia del Suelo, 2020-11-06)La influencia de la mineralogía y la granulometría del material parental en las características edáficas son particularmente importantes en suelos jóvenes desarrollados en superficies del Pleistoceno o más recientes. Así, ... -
A meta-frontier approach to measuring technical efficiency and technology gaps in beef cattle production in Argentina
(2015-08-09)In this paper the stochastic metafrontier method is applied to estimate technical efficiency (TE) and metatechnology ratios (MTR), in beef cattle production for three distinct regions in Argentina. A deterministic stochastic ... -
Mineralogía de la fracción arena de los suelos y sedimentos superficiales de la Región Pampeana. Una revisión.
(Asociación Argentina de la Ciencia del Suelo, 2022-11-15)Se efectuó una revisión de la literatura existente sobre la composición mineralógica de la fracción arena de suelos y sedimentos superficiales de la región pampeana. Se seleccionaron diversos componentes de las fracciones ... -
Nitrate pollution in dairy farms and its impact on groundwater quality in a sector of the Pampas plain, Argentina
(Springer, 2020)The aim of this work is to evaluate the nitrate content and its impact on groundwater quality used for supply in dairy farms in a sector of the Pampas Plain in relation to specific point sources of pollution. Samples were ... -
Pathotype and SSR variation in Phytophthora sojae from the Argentinean Pampas
(Wiley, 2020-04)Genetic variation in Phytophthora sojae was compared between northern (NPS) and southern (SPS) Pampeana sub‐regions, in the core soya bean region of Argentina. Ninety‐three isolates from plants and soil were evaluated in ... -
¿Qué ocurrió con la eficiencia agrícola en la región pampeana argentina entre 1988 y 2002?
(2015-05-21)Este trabajo tiene como objetivo medir diferencias en eficiencia técnica de partidos/departamentos de la región pampeana que producen los cuatro cultivos principales maíz, girasol, trigo y soja. Para ello se estimaron ... -
Sensitivity analysis of the pesticide in water calculator model for applications in the Pampa región of Argentina
(Elsevier, 2020-01-01)Despite the widespread use of pesticides in the Pampa region of Argentina, mathematical models are rarely employed to predict pesticide fate due to the lack of regionally tested models and the absence of readily available ... -
Sistemas ganaderos familiares de la Región Pampeana
(Ediciones INTA, 2022-05)Los sistemas ganaderos familiares son un tipo especial dentro de la categoría Agricultura Familiar. Son pluriactivos, ocupan el territorio y generan fuentes de trabajo. Ante el escenario productivo nacional, la ganadería ... -
Soil compaction alleviation by deep non - inversion tillage and crop yield responses in no tilled soils of the Pampas Region of Argentina. A meta - analysis
(Elsevier, 2021-05-03)No till is considered part of the good management practices recommended in conservation agriculture. Regardless of the benefits of this practice, shallow compaction or soil hardening by farm machinery traffic can lead to ... -
Soil moisture evaluation over the Argentine Pampas using models satellite estimations and in - situ measurements
(Elsevier, 2020-08-05)Study region: The Pampas region is located in the central-east part of Argentina, and is one of the most productive agricultural regions of the world under rainfed conditions. Study focus: This study aims at examining how ... -
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 ... -
Soybean in rotation with cereals attenuates nitrous oxide emissions as compared with soybean monoculture in the Pampas region
(Elsevier, 2021-11)Nitrous oxide (N-N2O) emissions in the agricultural sector represent ca. 25% of total N-N2O emissions on a global scale. In Argentina, information on agricultural emissions is scarce, and thus, N-N2O emissions are estimated ... -
