With water in very short supply maybe it time to learn a little more about drip irrigation. Elnard S. Ympal, a TESDA student had a good year regarding water use. What made his farm unique was his drip irrigation innovation. He used recycled plastic empty soft drink bottles for his modified drip irrigation (this innovation made him the 2010 National Outstanding Young Farmer) – he aspired to innovate this technology due to scarcity of water supply . I will be experimenting with coke bottles in the next couple of weeks to see what may work for the gardeners here. Please post you ideas also. Watching the attached U Tube may give you some thoughts. I like the idea of filling the bottles and walking away for the day. With the current heat cycle it is a job keeping everything wet.
