Maximizing application efficiency (Ae) of irrigation systems depends mostly on the irrigation manager’s ability to:
1. Reduce and/or eliminate runoff.
2. Reduce deep percolation below the root zone.
3. Overcome the infi ltration variability of the soil surface.
4. Optimize irrigation scheduling.
Presently, the subsurface drip irrigation (SDI) method is the only method capable of giving a manager this…
