Abstract/Contents:"The purpose of the study was to quantify evapotranspiration of several varieties of turfgrass, under adequate moisture conditions and with adequate fertility, for use with SMART irrigation controllers. Small weighing lysimeters were planted to 10 different turfgrass species or mixes in 2010, including 9 cool season grasses and 1 warm season mix, with four replicates of each turfgrass. Measured daily ET was compared to ETos calculated using data from an adjacent weather station and the standardized Penman-Monteith equation. The results from 2011 and 2012 are presented. Each lysimeter is centered in a 4-ft by 4-ft plot of the same grass variety. All grasses are mowed to the same height of 3 inches. The lysimeters each consist of a PVC shell containing a 12-inch diameter, free-draining sandy loam soil core having a 20-inch rooting depth. The lysimeters are continuously weighed in-place by electronic load platforms connected to a data logger. Irrigation is applied via high uniformity sprinklers and measured through a flow meter monitored by a data logger. All turfgrasses are irrigated on the same schedule and are managed to avoid soil moisture induced stress all received the same base watering. As needed, supplemental hand watering of each individual lysimeter was accomplished to bring each back to field capacity following each irrigation event. A table of the average ratio of measured turfgrass evapotranspiration to calculated ETos over the growing season is presented in the Summary."
