PMDI SUCCESS:USING A DRAG HOSE SYSTEM CUTS WATER COSTS WHILE BOOSTING YIELDS.

摘要

As a dealer for Raaft tracks (an aftermarket product to keep irrigation pivot tires from creating ruts in the field), Bob Gruner could have mixed feelings about the PMDI system he installed on a '/2-mile pivot nearly two years ago. Officially known asPrecision Mobile Drip Irrigation, the T-L Irrigation system consists of in-line drip hoses in place of nozzles or sprinkler heads, which are dragged by the center pivot or lateral-move system.In effect, PMDI technology combines the lower cost of pivot irrigation with the proven efficiency of drip irrigation for total water efficiency that approaches 95%.
