Unformatted text preview: p = 0.9 MPa in all cases). Note that oak has a taproot that accesses the water table at a depth exceeding 100 cm . In which of these situations is the assumed equilibrium between leaf and soil water potential least likely? Why? Corn on Potato on Oak on glacial till, Loamy soil: outwash sand: 0-100 cm depth: p = -0.5 MPa p = -1.8 MPa p = -1.1 MPa s = -0.3 MPa s = -0.1 MPa s = -0.2 MPa >100 cm depth: p = -0.3 MPa s = -0.1 MPa...
