Effective On-Farm Irrigation Scheduling in the Humid Southeastby Ted W. Tyson, Auburn Univ, United States,

Abstract: An extension demonstration of a checkbook type irrigation scheduling system using a personal computer and spread sheet is described. The system incorporates typical crop water use curves, field measured available soil moisture, rainfall, and net applied irrigation. Basic soil survey information and commercially available soil moisture sensors provide available soil moisture input. Effective rainfall is monitored and anticipated irrigation dates are projected. Rainfall is the only climatic factor monitored and used. The system provides an effective low cost, low technology procedure that can be easily understood and used by irrigators in the southeast. Patial funding to demonstrate this scheduling system was provided by the Alabama Department of Economic and Community Affairs-Science Technology and Energy Division. The irrigation energy management and scheduling demonstration program is beginning its third year.
