Hydraulic redistribution of soil water by roots of two desert riparian phreatophytes in northwest China’s extremely arid region
As deep water uptake is limited by the low densities of fine roots at the subsoil layer at high evaporative demand, hydraulic redistribution (HR) is another possible mechanism that could account for the lack o...
