(2014-12)Background and aims: The aim of this work was to evaluate the ability of P fertilization and phosphate-solubilizing bacteria (PSB) inoculation to promote the growth of L. tenuis in typical soils of the Salado River Basin ... -
Alteración de las propiedades mecánicas de un Ustochrept Udértico tratado con agua enriquecida en sodio
(Ediciones INTA, 2015-04)El riego con aguas con alto contenido de sodio puede provocar el deterioro de las propiedades físico-mecánicas de los suelos. En el presente trabajo se trató de evidenciar el efecto del tratamiento con agua rica en sodio ... -
Mejora de propiedades físicas por el uso de especies megatérmicas en un suelo sódico templado
(2015-06)Las especies megatérmicas pueden disminuir el pH del suelo y los niveles de sodicidad cuando se implantan en suelos sódicos, pero poco se sabe acerca de su capacidad para mejorar la condición física de suelos sódicos ... -
Phosphorus fertilization of a grass-legume mixture: effect on plant growth, nutrients acquisition and symbiotic associations with soil microorganisms
(2015-09)Adding P on Lotus tenuis and Festuca arundinacea, pure or mixed, on growth, nitrogen (N) and phosphorus (P) acquisition and associations with soil microorganisms was studied to investigate the establishment of Lotus for ... -
Impacto del tránsito en dos sistemas de siembra
(2015-12)Los sistemas productivos agrícolas presentan altos niveles de mecanización con tractores y máquinas cada vez más pesados. Como consecuencia, la compactación de los suelos es un problema emergente, dando como resultado el ... -
Herbicide-mediated promotion of Lotus tenuis (Waldst. & Kit. ex Wild.) did not influence soil bacterial communities, in soils of the Flooding Pampa, Argentina
(2016-02)Promoting the forage Lotus tenuis is an appealing alternative to meet the needs for cattle production in the Flooding Pampa region, Argentina. This agricultural practice requires herbicides application to remove plant ... -
Frequency of Neospora caninum infections in beef cow–calf operations under extensive management
(2016-03-30)The aim of this study was to evaluate the frequencies of Neospora caninum horizontal and vertical transmissions in beef cow–calf operations under three different extensive management systems: group A: 0.75 head per hectare ... -
Temporal variation of soil sorptivity under conventional and no-till systems determined by a simple laboratory method
(2017-05)Soil water sorptivity (S) is an important property that measures the soil capacity to take water rapidly under capillary forces. Usually S is not included in soil laboratory routine experiments because there is not a widely ... -
Producción de biomasa, cobertura y calidad forrajera de Chloris gayana y Panicum coloratum en un suelo alcalino sódico de la Depresión del Salado
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2017-12)La expansión agrícola, que viene ocurriendo en la región durante las últimas dos décadas, no solo redujo considerablemente la superficie ganadera, sino que la desplazó hacia zonas marginales. En este contexto, la incorporación ... -
Respuesta de hongos benéficos del suelo asociados a Lotus tenuis a la aplicación de glifosato
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2017-12)En los últimos años se está adoptando la práctica de promoción de Lotus tenuis a través de la aplicación de glifosato en pastizales de La Pampa Deprimida debido a su importante aporte en cantidad y calidad de forraje. Sin ... -
Temporal Variation of Soil Physical Quality under Conventional and No-Till Systems
(2018-04)Determination of soil physical quality (SPQ) is very important because it is related to many important soil processes. However, it is not clear which indicators should be considered in this evaluation, and information about ... -
Pureza física y germinación de cariopses de Chloris gayana Kunth y Panicum coloratum L. cosechados de plantas cultivadas en un suelo alcalino-sódico
(2018-04)El objetivo del estudio fue evaluar la pureza física, el porcentaje de germinación (G), la velocidad de germinación (VG) de cariopses de Chloris gayana cv. Finecut (Cg) y Panicum coloratum cv. Klein Verde (Pc) recolectados ... -
White muscle disease in three selenium deficient beef and dairy calves in Argentina and Uruguay
(Centro de Ciências Rurais, Universidade Federal de Santa Maria, 2018-05)White muscle disease (WMD), nutritional myodegeneration or enzootic muscular dystrophy, is a nutritional condition associated with selenium and/or vitamin E deficiency in ruminants. These elements are constituents of the ... -
Effect of protein restriction of bovine dams during late gestation on offspring postnatal growth, glucose-insulin metabolism and IGF-1 concentration
(2018-06)The objective of this study was determine whether the amount of protein provided to cows during late gestation would affect postnatal growth and lead to changes on glucose, insulin and insulin-like growth factor concentrations. ... -
Effect of protein restriction of Angus cows during late gestation: Subsequent reproductive performance and milk yield
