Drip Vs. Furrow Irrigation Of Cotton On Sandy Soil With 1/4 Mile Runs - Includes: Yield Monitoring, Remote Sensing, And Electronic Soil Survey, William R. Detar, S. J. Maas, G. J. Fitzgerald

William R DeTar

Subsurface drip irrigation was compared to furrow irrigation of cotton on 990-ft runs for 4 seasons on sandy soil. The first furrow irrigation after planting was difficult (as expected) and wasted a lot of water, up to 4 in. The drip system was less efficient than expected due to the startup time required. On the average for the season, the furrow system used 10.5 in. more water that the drip system, a difference which is very similar to results from published short-run (300 ft) tests. There was no difference in yield between the drip and furrow treatments. There were extreme …
