Land tenancy, soybean, actors and transformations in the pampas: A district balance
(2015-06)In Argentina, the recent expansion of agriculture has turned into an extreme process almost completely dominated by soybean. The magnitude and speed of soybean expansion are believed to be the main drivers behind social, ... -
Lecciones de cuatro meta-análisis globales sobre la restauración de la biodiversidad y los servicios ecosistémicos
(Asociación Argentina de Ecología, 2017-04)La restauración ecológica se utiliza a menudo para recuperar los niveles de biodiversidad y de servicios ecosistémicos (SE) en ecosistemas degradados. En general, los resultados de la restauración ecológica se pueden estimar ... -
Lectin binding patterns and immunohistochemical antigen detection in placenta and lungs of Brucella abortus-bovine infected fetuses
(2018)Lectin binding relies on the affinity of these substances for specific terminal sugars. The method facilitates the identification of complex structures to which the terminal sugar attaches and may reveal physiological or ... -
Linking farmers' management decision, demographic characteristics and perceptions of ecosystem services in the Southern Pampa of Argentina
(Elsevier, 2020-03-15)In the Pampean region of Argentina, uncultivated areas with spontaneous vegetation, such as the sierras (low hills), are important sites for nature conservation. In the last decades, the “agriculturization” process has ... -
Linoleic acid stimulates neutral lipid accumulation in lipid droplets of maturing bovine oocytes
(Elsevier, 2013-03-01)Linoleic acid (LA) is a polyunsaturated fatty acid present in high concentrations in bovine follicular fluid; when added to maturation culture media, it affects oocyte competence (depending on the type and concentration ... -
Longitud de la vaina como determinante de la calidad de hojas de festuca arundinacea durante un período de rebrote
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2014-08)Se evaluó la calidad nutritiva de las láminas de rebrotes de Festuca arundinacea provenientes de dos tratamientos de corte de distinta altura de remanentes (40 mm y 100 mm). El experimento se realizó en 500 macetas al aire ... -
Lotus tenuis (Waldst. et Kit), estudio para un manejo con múltiples propósitos
(Ediciones INTA, 2020-12)El uso de cultivos con múltiples propósitos es una opción que permite obtener de un mismo sistema de producción diferentes servicios ecosistémicos. El objetivo del presente trabajo fue combinar fechas de corte en un cultivo ... -
Low temperature differentially affects tillering in spring and winter wheat in association with changes in plant carbon status
(Wiley, 2015-03)The higher tillering potential of winter wheat cultivars as compared to spring ones has been attributed to an earlier tillering onset in the former. Tillering in grasses is known to depend on temperature and light environment, ... -
Maize grain yield components and source-sink relationship as affected by the delay in sowing date
(Elsevier, 2016-11)Delaying maize (Zea mays L.) sowing date can diminish grain yields through reductions in the number, size and activity of growing grains (sink strength) and/or reductions in the assimilate supply (source capacity) to grains ... -
Maize transpiration efficiency increases with N supply or higher plant densities
(Elsevier, 2021-03-08)Most of the studies addressing the influence of management practices on seasonal crop water use efficiency (i.e., the ratio between shoot biomass and evapotranspiration in a seasonal scale, WUE(B, ET, s)) have focused on ... -
Maize–soybean intensification alternatives for the Pampas
(2014-06)Cultivating multiple crops as a land use alternative could increase system productivity and sustainability, providing options to soybean monoculture for the Argentinean Pampas. This study evaluates the performance of ... -
Management effects on glyphosate and AMPA concentrations in the PM10 emitted by soils of the central semi-arid region of Argentina
(Elsevier, 2020-12)In soils of semi-arid regions, different amounts of glyphosate are applied, and this substance tends to be absorbed on the topsoil exposed to erosion. The objective of this study was to analyze the effects of land management ... -
Meat quality traits in the Greater rhea (Rhea americana) as influenced by muscle, sex and age
(2018-02)Meat from the Greater rhea (Rhea americana) could compete with traditional red meats, diversifying the market of protein products of animal origin. The meat from 32 rheas was used to study quality aspects and this included ... -
Methodological performance of selenium determination in ruminal fluid by hydride generation atomic absorption spectroscopy
(Ediciones INTA, 2021-04)Selenium (Se) is a trace element used by multiple enzymes. In ruminants, Se present in food is released to ruminal fluid allowing its absorption in the small intestine. Se release may be analysed by hydride generation ... -
