摘要

Tim Schmeeckle is learning to grow corn with less water. Precision-irrigation management is helping him and other farmers apply the right amount of water on every part of the field. Variable-rate irrigation (VRI) adjusts water application depth for differences in soil water-holding capacity, topography and yield potential. The goal is to boost crop production while conserving an expensive and increasingly scarce resource. "Even in a drought year," Schmeeckle says, "I'm conserving water."
