home consumers in College Station, TX, it was estimated that more than 24 to 34 million gallons of excess water, that is water in excess of an irrigation coefficient of 1.0 of the yearly reference evapotranspiration, were used annually for landscape

Proper irrigation management is critical to growing quality turfgrass with limited water in arid and semiarid regions. Deficit irrigation, defined as applying water in amounts less than the reference evapotranspiration rate, is an irrigation
