Curiosity makes me comment, at the slow rate of 3/4 gallon per hour, the
system delivers the annual requirment in 16 hours.  I must assume that
the drip is controlled for dry conditions, and that there is a limited
delivery time scheduled over weeks, or months. 

Anyone have more information on drip systems for trees?  High value
species plantations (walnut comes to mind) may benefit from such a
system.
