The compensatory root water uptake conductance (Kcomp) () characterizes how a plant compensates its water uptake under heterogeneous water potential. It controls the root water uptake in a soil where the water potential is not uniform.A simple three-dimensional macroscopic root water uptake model based on the hydraulic architecture approach Couvreur, V.; Vanderborght, J.; Javaux, M.
