WebRoot pressures ranged between 0.13 and 0.40 MPa. Hydrostatic pressure relaxations were produced by turning the metal rod of the probe rapidly to induce a hydrostatic pressure pulse (± Δ P of 0.05 MPa) in the root xylem. Osmotic relaxations were induced by adding 20 or 25 mM NaCl to the root medium.

WebRoot pressure relies on positive pressure that forms in the roots as water moves into the roots from the soil. Water moves into the roots from the soil by osmosis, due to the low solute potential in the roots (lower Ψs in roots than in soil). This intake o f water in the roots increases Ψp in the root xylem, driving water up.
