        <dc:description>AUTOMATION of surface irrigation offers exciting
possibilities for today's irrigation farmer. It provides
a means for improving  water use efficiency
and cutting labor requirements. Excessive water is often
used in current irrigation methods; water application
efficiencies usually do not average over 50 to 60 percent. Although
many factors affect irrigation efficiency, the water
facilities and management practices used by the individual
operator have the greatest effect.
Competition for available national water supplies is increasing
rapidly. Irrigators eventually may have to justify
their use of water. They may not always be permitted to
use nearly twice the amount required to satisfy crop consumptive
use requirements.</dc:description>
