title: Impedance to Water Movement in Soil and Plant.
abstract: The total impedance to water movement from the soil into the plant was compared with that predicted for the soil alone. When soil suction was below 0.6 bar, the impedance was largely in the plant. When suction was greater than 1 or 2 bars, the soil became the limiting factor. Water movement to the plant roots takes place primarily in the liquid phase.
