This paper will focus on a commercial process for making decisions on the selection of the type of variable rate irrigation or even if variable rate irrigation makes sense for a particular field. Included will be examples of specific fields and a comparison of the projected benefits, costs and payback of different types of variable rate irrigation. Data from the 2011 season will be presented to support the decision process. In addition various tools will be reviewed for comparing variable rate irrigation choices and selection.
