A phreatophyte is a deep-rooted plant that obtains a significant portion of the water that it needs from the phreatic zone or the capillary fringe above the phreatic zone. Phreatophytes are plants that are supplied with surface water and often have their roots constantly in touch with moisture. A phreatophyte is one that absorbs its water from a constant source on the ground.

Phreatophyte Evapotranspiration and its Potential Reduction Without Eradication The benefits of AT spraying of phreatophytes will be small where existing water supplies meet demands at reasonable cost. Water can, however, cost several hundred $/lOOO m3, depending on distance from source, pumping energy, and other factors. …Adaptations of Desert Annuals.
