Estimación del volumen sin corteza en Eucalyptus grandis utilizando modelos de regresión con variables instrumentales en dos etapas de plantaciones de la Mesopotamia argentina
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2015-08)En este trabajo se ajustaron modelos de predicción de volumen total sin corteza (vtsc) y volumen total con corteza (vtcc) de árboles individuales en forma simultánea. El vtcc se ajustó en función de la altura del árbol (h) ... -
Producción de plantines de petunia (Petunia híbrida) en sistema flotante
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2015-08)El sistema flotante es un tipo de producción hidropónica de plantines muy utilizado en el sector tabacalero argentino, pero en el sector florícola es nuevo y no está muy estudiado y difundido. Este sistema permite reducir ... -
Techos verdes, sistemas extensivos que requieren equipos profesionales multidisciplinarios
(2015-08)Desde hace unos años hay una tendencia cada vez más fuerte a la búsqueda de estructuras naturadas en las grandes urbes. Esto responde a un conjunto de necesidades y tendencias; por un lado, es la toma de conciencia de los ... -
Influence of fuel conditions on the occurrence, propagation and duration of wildland fires: A regional approach
(2015-09)Wildfires affect Earth's surface every year. Fuels conditions influence fire occurrence and behavior; therefore, their characterization is important for fire risk studies. We analyzed vegetation conditions influencing fires ... -
Total and aboveground radiation use efficiency in C3 and C4 grass species influenced by nitrogen and water availability
(Wiley; Japanese Society of Grassland Science, 2015-09)Absorbed solar radiation and radiation use efficiency (RUE) can be used to estimate net primary productivity of terrestrial ecosystems. In ecosystems dominated by grasses, belowground productivity cannot be neglected in ... -
Presencia de Mimosa regnellii (Mimosoideae, Leguminosae) en Argentina
(Sociedad Argentina de Botánica, 2015-09)En el presente trabajo se confirma formalmente la presencia de Mimosa regnellii y se cita por primera vez a M. regnellii var. exuta para la Flora Argentina. Esta especie y su variedad se distribuyen en el extremo oriental ... -
Carta de suelos de la República Argentina, Hoja 2563-13-2 Las lajitas, Departamento Anta, provincia de Salta. Escala 1:50000
(Ediciones INTA, 2015-09-01)El conocimiento del suelo, de sus características y aptitudes, así como de su distribución geográfica dentro de un área, es fundamental para planificar racionalmente su uso. Las cartas de suelo son la forma tradicional de ... -
Changes in evapotranspiration and phenology as consequences of shrub removal in dry forests of central Argentina
(Wiley, 2015-10)More than half of the dry woodlands (forests and shrublands) of the world are in South America, mainly in Brazil and Argentina, where in the last years intense land use changes have occurred. This study evaluated how the ... -
Selection of a suitable probability model for the analysis of biochemical data from soil
(Sociedad Argentina de Estadística, 2015-10-06)Compacted soil in Argentine and other countries causes serious loss of agricultural production. In previous studies we used biological indicators of soil quality to describe the soil in different systems of agricultural ... -
Biological profile from soil using components analysis
(Sociedad Argentina de Estadística, 2015-10-06)It is known that principal components analysis is used as a mathematical procedure that transforms a set of correlated response variables into a new set of non-correlated variables known as main components. The sensitivity ... -
Both Volatiles and Cuticular Plant Compounds Determine Oviposition of the Willow Sawfly Nematus oligospilus on Leaves of Salix spp. (Salicaceae)
(Springer, 2015-11)Plant volatile organic compounds play a role in selection of host plants by herbivorous insects. Once the insect reaches the plant, contact cues determine host acceptance. Although the willow sawfly Nematus oligospilus ... -
