Abstract
Water conservation, distribution of chemicals through irrigation water and the increasing popularity of low application rate irrigation systems are all important factors pointing up the need for more precision in irrigation management which in turn is dependent upon accurate estimates of expected evaporation losses. Data has been obtained to predict the independent effect of water application rate, air (wind) velocity, water temperature and dry bulb and dew point temperature of the ambient air on evaporation losses by water droplets and water droplets in combination with plant intercepted water. By far the most influential factor on evaporation losses is the rate of application. Results indicate evaporation losses are about 60% for low application rates (0.15 iph) with climatic conditions typical of Florida and when plant foliage is present to intercept most of the applied water.
