Evapotransportation, Crop Coefficients, and Leaching Fractions of Irrigated Desert Turfgrass Systems

Reducing irrigation volumes on turfgrass in an arid environment requires close attention to environmental demand. The objective of this research was to quantify the water balances of three turfgrass sites controlled by an evapotranspiration (ET) feedback system and local management. Additional objectives included calculating leaching fractions (LF), crop coefficients (Kc), water savings, and quantifying the variability in potential evapotranspiration (et 0 ). A 2-yr study was conducted on three turfgrass sites in southern Nevada growing common bermudagrass [Cynodon dactylon (L.) pers.] overseeded with perennial ryegrass (Lolium perenne L.) (...)
