Abstract or Description:
Many growers in Arizona are switching from surface to drip irrigation. This change requires many changes in water management. One of the changes that growers are having the most difficulty with is the concept of applying gallons of water instead of inches. This paper helps growers make this conversion from inches to gallons and then back again. An accompanying EXCEL program, available on the web, will help growers determine run times and application amounts.
This publication discusses the relationship between gallons and inches, and the hours of operation for drip irrigation systems used with rows crop production. Examples are given on how to determine application amounts and hours of operation needed to apply a targeted amount of water. Simple formulas that can be used on a hand-held calculator are given, as well as the option to download a Microsoft Excel program from the Internet.
