Abstract

A major pathway of water loss from plants is by transpiration, which accounts for 99 percent of the water taken up by plant roots. This water is lost from the immediate area where the plant is growing, since it passes via the atmosphere to some other point in the hydrologic cycle. Because the water that is transpired is essentially pure, salts in the soil water system become more concentrated.
