Capacity and Intensity Indicators to evaluate the effect of different crop sequences and cover crops on soil physical quality of two different textured soils from Pampas Region
(Elsevier, 2021-11)Soil physical degradation is a current problem in Molisols of the Pampas Region under no-tillage (NT), that has been related to over-simplified agricultural systems with scarce or no rotations and long winter bare fallows. ... -
Estrategias para descompactar el suelo en la región semiárida pampeana: efecto residual en la infiltración básica y en el rendimiento = Strategies to decompact the soil in the semi-arid pampas region: residual effect on basic infiltration and yield
(Facultad de Ciencias Agrarias, Universidad Nacional del Litoral, 2023-01-01)La compactación del suelo es una problemática cada vez más recurrente y en la actualidad genera gran preocupación entre los productores y colegas de diferentes regiones del país. El presente trabajo consistió en evaluar, ... -
Evaluación de indicadores edáficos en áreas normales y bajo manchón de pasturas en la región semiárida pampeana
(Asociación Argentina Ciencias del Suelo, 2024-05-21)Los parches o manchones caracterizados por menor producción y persistencia de las pasturas perennes son cada vez más frecuentes. El objetivo fue evaluar indicadores de suelo en sectores bajo manchón con respecto a áreas ... -
Evaluación de propiedades hidráulicas y edáficas en fondos de represas ganaderas
(Estación Experimental Agropecuaria La Rioja, INTA, 2019-11)El objetivo del presente trabajo fue evaluar el comportamiento de parámetros hidráulicos y edáficos en fondos de represas y resaltar la importancia que revisten estos procesos en el desarrollo de un plan de manejo de estas ... -
Functional responses to multiple sequential abiotic stress (waterlogging-drought) in three woody taxa with different root systems and stress tolerance
(Wiley, 2023-06-23)There is generally a trade-off in the resistance to drought and to waterlogging. However, several species are sequentially subjected to both stressors in many environments. We evaluated the ecophysiological strategies to ... -
Hydraulic conductivity and pore connectivity. Effects of conventional and no-till systems determined using a simple laboratory device
(Elsevier, 2019-03-01)Soil hydraulic conductivity is a property that describes how easily water can move through a porous space and its determination is important because it controls many soil hydrological processes. The objectives of this work ... -
Influencia de seis portainjertos de vid sobre el comportamiento vitícola de la cv. Malbec y estudio de las relaciones hídricas que se establecen
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2008)El uso de portainjertos en la vid se ha difundido por su resistencia a filoxera y nemátodos, pero también por su tolerancia a condiciones adversas del suelo. Por otro lado, los portainjertos modifican las relaciones ... -
Land-use change affects soil hydro-physical properties in Mollisols of semiarid Central Argentina
(Elsevier, 2021-06-01)The objective of the present study was to describe the relationships between soil physical properties and to identify variables that determine the pore system and hydrological functions which are specifically important in ... -
Prediction of hydraulic conductivity loss from relative water loss: new insights into water storage of tree stems and branches
(Wiley, 2019-04)More frequently occurring, drought waves call for a deeper understanding of tree hydraulics and fast and easily applicable methods to measure drought stress. The aim of this study was to establish empirical relationships ... -
Quality assessment of irrigation water under a combination of rain and irrigation
(Elsevier, 2015-09)Supplementary irrigation is one of the proposed management practices to increase the area under grain production mainly in the Humid Pampas (HP). The most common source of irrigation water in the HP comes from groundwater ... -
Short- and long-term responses to seasonal drought in ponderosa pines growing at different plantation densities in Patagonia, South America
(2012-12)Trees drought responses could be developed in the short- or in the long-term, aiming at sustaining carbon fixation and water use efficiency (WUE). The objective of this study was to examine short- and long-term adjustments ... -
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 ... -
Variation of wood density and hydraulic properties of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) clones related to a heat and drought wave in France
(Elsevier, 2009-01)Drought response of three Douglas-fir clones (slow, intermediate and fast growing) inhabiting two different climatic regimes in France was examined.We used the hydraulic conductivity and the percent loss of conductivity ... -
Wood density and anatomy of three Eucalyptus species: implications for hydraulic conductivity
(2017)Aim of the study: To characterize wood anatomical traits of three Eucalyptus species that differ in wood density and ecological requirements, and to examine the relationships between some anatomical features, wood density, ... -
Wood structure, xylem functionality and growth of six Salix clones in two sites with different environmental stress in Argentina
(Sociedade de Investigações Florestais, 2018)The aims of the study were to evaluate the effects of abiotic stress (plantation site) and genotype (clone) on the wood anatomy and density of six Salix (willow) clones at three ages (2, 7, and 12 years), and the impact ...
