Washington State University reports that professor Pete Jacoby has developed a Direct Root-Zone irrigation (DRZ) system that could cut vineyard water use by 35%. The system utilizes vertical tubes buried one to four feet in the soil to deliver water directly to the root zones of individual plants. Field research has shown that the system can be a viable option for growers in arid southcentral Washington and other similar climates worldwide.
