T-L’s patented technology has successfully married center pivot technology with drip irrigation. PMDI™ consists of in-line drip hoses spaced 60”, 40” or 30” between lines being dragged through various crops by a center pivot or linear move irrigation system.
PMDI™ combines the efficiency of surface drip irrigation (95%) with the flexibility and economics of center pivot irrigation. The system consists of in-line drip hoses, in place of nozzles or sprinkler heads that are dragged by the center pivot or lateral-move system. As the hoses are pulled through the field, emitters deliver an even water pattern across the full length of the pivot or linear system. In effect PMDI™ technology combines the lower cost of center pivot irrigation with the proven efficiency of drip irrigation for total water efficiency that approaches 95%. There are two main advantages of precision drip irrigation: Overall Water Efficiency. With the drip line design, you eliminate evaporation and wind drift associated with traditional sprinklers because wind will not affect it as it applies water at a super efficient 95%. You get all the efficiency of surface drip at the much-reduced cost per acre price of center pivots. In many soils and cropping practices, deep wheel tracks on pivots and linears are a problem. With PMDI™, the drip lines water behind the wheels so the tires run on dry ground.
