Hydraulic conductivity of Molisolls irrigated with sodic-bicarbonated waters in Santa Fe (Argentine)
(Elsevier Science, 2007-03)
Irrigation waters with high sodicity and low salinity levels may deteriorate soil physical properties, consequently affecting the water movement in the soil. The objectives of this study were: (i) to evaluate the effect ...
Nutrient enrichment changes water transport structures of savanna woody plants
(IOP Publishing, 2021-02)
Brazilian savanna is a seasonally dry biome, highly diverse and distributed mainly on nutrient-limited soils. Interactions between water stress and nutrient availability are important evolutionary filters in these environments. ...
Winter cover crops effects on soil organic carbon and soil physical quality in a typical argiudoll under continuous soybean cropping
(Sociedade Brasileira de Ciência do Solo, 2020-11-27)
The massive adoption of no-tillage (NT), along with the simplification of the cropping sequences has led to physical and chemical degradation of soils. To recover degraded soils, cover crops have been proposed as an ...
Genetic variation of xylem hydraulic properties shows that wood density is involved in adaptation to drought in Douglas-fir (Pseudotsuga menziesii (Mirb.))
(Springer, 2011-05)
Relationships between wood density and hydraulic efficiency and safety (hydraulic specific conductivity and vulnerability to cavitation, respectively) could clarify the physiological process explaining the impact of density ...
On the multiscale characterization of effective hydraulic conductivity in random heterogeneous media: A historical survey and some new perspectives
(Elsevier, 2020-06)
In large scale heterogeneous aquifer simulations, determining the appropriate coarsening scale λ to define an effective hydraulic conductivity Keff is a challenging task, that involves a trade-off between accuracy and cost. ...
First insights into the functional role of vasicentric tracheids and parenchyma in eucalyptus species with solitary vessels: Do they contribute to xylem efficiency or safety?
(Oxford University Press, 2016-07)
The relationship between hydraulic specific conductivity (ks) and vulnerability to cavitation (VC) with size and number of vessels has been studied in many angiosperms. However, few of the studies link other cell types ...
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. ...
Macroscopic properties of soils controlled by the diffuse double layer around particles
(Trade Science Inc., 2010-06)
Physic and chemical properties ofliquids and particle-fluid interaction (PFI) mechanisms control relevant soil properties. Chemical properties of pore fluids affect mainly the structure and hydraulic conductivity of fine ...
Glyphosate dynamics in a soil under conventional and no-till systems during a soybean growing season
(Elsevier Science, 2018-08)
Glyphosate (GLY) is a non-selective herbicide, heavily used world-wide in agriculture, especially under no-tillage (NT) management. The objectives of this work were i - to determine the temporal and vertical variation of ...
Water relations and hydraulic architecture in Cerrado trees: adjustments to seasonal changes in water availability and evaporative demandRelações hídricas e arquitetura hidráulica em árvores do cerrado: adequação às variações sazonais de disponibilidade hídrica e de demanda evaporativa
(Brazilian Society of Plant Physiology, 2008-09)
We determined adjustments in physiology and morphology that allow Neotropical savanna trees from central Brazil (Cerrado) to avoid water deficits and to maintain a nearly constant internal water balance despite seasonal ...
