Probabilidad de ocurrencia de temperaturas máximas y mínimas medias decádicas en Inta Paraná y zona de influencia (Entre Ríos, Argentina)
(Facultad de Ciencias Agropecuarias, Universidad Nacional de Córdoba, 1995)La producción agropecuaria depende en gran medida del comportamiento de las variables meteorológicas durante el ciclo productivo. Sin embargo ese comportamiento, aunque aleatorio, responde a ciertos modelos probabilísticos ... -
Indicadores de calidad para dos suelos con características vérticas de Entre Ríos (Argentina) = Quality indicators for two soils with vertic characterstics in Entre Ríos (Argentina)
(Instituto Universitario de Xeoloxía, 2007)Nowadays, in the central northern region of Entre Ríos farmers clear forest land, both for cat tle rising and crop production, which generates an important pressure on natural resources. Soil quality constitutes one of the ... -
Distribución de poros en un suelo vertisólico de uso arrocero = Pore size distribution of a Vertisol cropped to rice
(Instituto Universitario de Xeoloxía, 2007)Vertisols and soils with vertisolic characteristics from Entre Ríos province (Argentina) display a high structural stability when supporting natural vegetation. This is mainly attributed to the effects of the colloidal ... -
Aplicación del modelo DRASTIC en la cuenca del arroyo Las Conchas, Entre Ríos
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2011-08)La demanda de la sociedad respecto al cuidado de la salud y del ambiente es cada vez mayor, requiriéndose la evaluación de potenciales impactos negativos producidos por las prácticas agropecuarias, entre ellos la contaminación ... -
Water and solar radiation productivity of double-crops in a humid temperate area
(Southern Cross Publishing, 2011-12)The intensification of agricultural systems including sequential double-crops provides a reliable platform to increase the water and solar radiation use in many humid temperate areas of South America, which are predominantly ... -
Defoliation affects soybean yield depending on time and level of light interception reduction
(Southern Cross Publishing, 2012-07)Light interception (mainly due to defoliation) during the critical growth periods of soybean may be a suitable index for calculating the economic injury level (ELI) rather than measuring the insect population or percentage ... -
Land use intensity and cropping sequence effects on aggregate stability and C storage in a Vertisol and a Mollisol
(2013)The relevant change in land use duemainly to the rapid expansion of soybean cropping towards areas traditionally occupied for livestock purposes or with native grasslands of South America may have negative consequences on ... -
Characterization of multispectral aerial images of sugarcane
(IOP Science, 2013)In this paper we present a implementation and characterization the status of sugarcane plantations based on the analysis of multispectral aerial images. Currently there are no precise techniques to estimate objectively the ... -
Critical bulk density for a Mollisol and a Vertisol using least limiting water range: effect on early wheat growth
(2013-01)The least limiting water range (LLWR) integrates crop growth-limiting values based on easily measurable parameters such as soil water content and bulk density (BD) and has been validated as a valuable soil physical quality ... -
Modelling long-term effects of cropping intensification reveals increased water and radiation productivity in the South-eastern Pampas
(Elsevier, 2013-08)Wheat/soybean double crop provides a reliable platform for cropping intensification in many subtropical and temperate areas, even in those with a short growing season as the South-eastern Pampas of Argentina. However, the ... -
Effects of fire disturbance on bird communities and species of mountain Serrano forest in central Argentina
(Taylor & Francis, 2014)In central Argentina, Serrano forest has a long history of fire disturbance; however, the impact of fire on avifauna remains unknown. We compared the avian–habitat relationships in forest patches with low, moderate, and ... -
Análisis productivo y reproductivo de vacas lecheras Holstein, Pardo Suizo y sus cruzas en un sistema a pastoreo = Analysis of production and reproduction of Holstein, Brown Swiss and their crossbreed dairy cows in a grazing system.
(Universidad Nacional del Nordeste. Facultad de Ciencias Veterinarias, 2014-06)El objetivo del trabajo fue comparar aspectos productivos y reproductivos de vacas pertenecientes a tres genotipos lecheros, en un sistema a pastoreo con suplementación de Entre Ríos, Argentina. Se analizaron datos ... -
Nitrógeno incubado en anaerobiosis y su relación con el nitrógeno orgánico en diferentes fracciones = Mineralizable nitrogen in anaerobiosis and its relationship with different organic n pools
(Asociación Argentina de la Ciencia del Suelo, 2014-07)Los diagnósticos de fertilidad nitrogenada usualmente utilizados no contemplan el aporte de la fracción orgánica del suelo. El nitrógeno (N) incubado en anaerobiosis (Nan), al igual que otras fracciones lábiles del N puede ... -
Stover quality and soil organic carbon in long-term nitrogen-fertilized maize
(Alliance of Crop, Soil, and Environmental Science Societies, 2014-09)Nitrogen fertilization often increases maize (Zea mays L.) grain yield but reduces the C/N ratio of stover returned to the soil, which may affect the soil organic carbon (SOC) balance. This study evaluated the long-term ... -
Nitrogen utilization efficiency in maize as affected by hybrid and N rate in late-sown crops
(2014-11)After the introduction of Bt-maize, late sowing is becoming an important strategy to stabilize yields in many areas of the Argentine Pampas. Increased nitrogen (N) availability and sharp reduction in radiation and temperature ... -
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 ... -
Soil quality impacts of current South American agricultural practices
(Society for Urban Ecology, 2015)Increasing global demand for oil seeds and cereals during the past 50 years has caused an expansion in the cultivated areas and resulted in major soil management and crop production changes throughout Bolivia, Paraguay, ... -
Differential susceptibility of Conyza bonariensis biotypes to glyphosate and ALS-Inhibiting herbicides in Argentina
