Boxes were mounted on poles so that plate surfaces were supported about 1 meter above the ground. Evaporation from each Bellani plate was measured on 19 precipitation-free days using a mass balance method. Evaporation from plates at the weather station was compared to that from plates at the four tees. Turf under and surrounding the weather station site is thin and nonirrigated, likely resulting in higher air temperatures. Tee 7 is surrounded by trees and shrubs, which limited wind movement and shaded the area, resulting in lower evaporation.
Results confirm that water demand can vary significantly across a golf course.
Weather data-generated ET information should be used as a guide for irrigation, realizing that various microclimates may require more or less water than predicted. Additional locations will be evaluated in 1996. Bellani plate evaporation at selected locations at the Manhattan Country Club in 1995.
