Irrigation News, 25: 31-36http://dspace.lib.cranfield.ac.uk/handle/1826/1675This paper compares the use of different methods for estimating reference evapotranspiration (ETo) for irrigation scheduling in the UK. Methods include use of long-term averages, daily weather data and evaporimeters. The results from a single trial in Silsoe in 1996 suggest that, with careful maintenance and measurement, a modified atmometer such as the ETgage, can give estimates of ETo which are close to those obtained using the Penman-Monteith equation.AtmometerETgageEvapotranspirationETArticle
