| Abstract/Contents: | "Excess water applied in urban areas is a major concern due to changing climates, population shifts, shifting resource needs, etc. In much of the cool-humid region, like Indiana, precipitation exceeds evaporative loss but supplemental irrigation is still required on high value landscapes due to intermittent acute dryness periods. Several automated weather stations' data were evaluated to determine potential seasonal water needs based on precipitation and evapotranspiration [ET] data. Central Indiana ET for April through October averages 663 cm whereas precipitation averages 688 cm - producing a net surplus of water, in theory negating the need for supplemental irrigation. However, supplemental irrigation is still applied to lawns - often in excess especially where 'set it and forget it' scheduling programs are utilized. Currently, a typical 465 m2 lawn with supplemental irrigation following a 'set it and forget it' schedule and applying 25.4 to 38.1 cm wk-1 may receive up to 11,800 to 17,700 L of water weekly. Seasonally, this method of supplemental irrigation may apply up to 940 cm of water. By contrast, a data-driven approach using local weather data and ET could result in significant savings by instead by applying 397.8 cm to 530.4 cm to the same 465 m2 lawn. This analysis shows that there is a demonstrable need to upend current supplemental lawn irrigation practices to allow for the implementation of optimized, technology driven irrigation techniques." |
