Frequently Asked Questions
Water potential is the potential energy of water per unit volume relative to pure water, often expressed in megapascals (MPa). It determines the direction of water movement in soil and plants.
The components are matric potential (due to capillary and adsorptive forces), gravitational potential (due to elevation), pressure potential (due to hydrostatic pressure), and osmotic potential (due to solutes).
A negative total water potential indicates water is bound or under tension; a positive value indicates free water under pressure. In soils, typical values range from 0 (saturated) to -1.5 MPa (permanent wilting point).
