Evapotranspiration from forage grass replacing native vegetation in the Gila River valley of Arizona
O.E. Leppanen
1981, Open-File Report 81-1018
Estimates of evapotranspiration from an area of forage grass, which had been planted to replace native vegetation of little economic value, were made daily for a 363-day period in 1969 and 1970. The measurement site was located in the Gila River valley in east-central Arizona. The forage, panigrass (Panicum antidotale...
