Managing irrigation spatially can enhance water conservation and optimize water applications. Information and guidelines are needed on how to spatially precision-apply irrigation water with these systems. In this research, we investigated using soil electrical conductivity (EC) to delineate management zones for spatial water applications using variable rate irrigation systems. Our preliminary results indicated potential correlations between soil EC, spatial plant growth, and stomatal resistance.
