3. Bubbler Irrigation In bubbler irrigation, water is applied to the soil surface in a small stream or fountain from an opening with a point-source discharge rate greater than surface or subsurface microirrigation of 12 L/h, but usually less than 250 L/h. Because the emitter discharge rate normally exceeds the infiltration rate of the soil, a small basin is required to contain the distribution of water (Fig. 12). The use of bubbler application is extensive in landscape irrigation systems, but is use in agriculture is currently limited.

In the 1991 ICID survey (Bucks, 1995), nearly all the countries indicated that microirrigation systems used in vegetable and field crops and in greenhouses would be more expensive than the same systems used on tree crops. In Japan, system costs for flowers and vegetables were as high as $16,000/ha. However, many of the countries indicated that an average installation cost for microirrigation systems was $2,000 to $4,000/ha. Estimates of operation and maintenance costs ranged from $100 to $800/ha-year.
