There are currently two major MDI (Mobile drip irrigation part 1) products on the market. These includes Dragon-Lines and Netafim whose product is termed PMDI.
Dragon-Line by Kansas-Based Teeter Irrigation Uses Netafim’s PMDI, The Water-Efficient, Yield-Boosting Solution That Dramatically Increases the Efficiency of Traditional Center Pivot Irrigation. Transforming the landscape of center pivot irrigation, a Precision Mobile Drip Irrigation (PMDI) system consists of Netafim’s DripNet PC™ dripline pulled through the field by a center pivot or linear move irrigation system. The driplines deliver water directly to the soil surface, virtually eliminating evaporation and wind drift and allowing for deeper percolation to the plant’s root zone.
Transforming the landscape of center pivot irrigation, the PMDI solution consists of Netafim’s industry leading DripNet PC™ dripline pulled through the field by a center pivot or linear move irrigation system. As the driplines are pulled behind the system, the integrated emitters deliver a uniform water pattern across the full length of the irrigated area. Because the driplines deliver water directly to the soil surface, evaporation and wind drift are virtually eliminated, allowing for more water to reach the soil surface and deeper percolation to the plant’s root zone. Furthermore, because the water is applied behind the center pivot wheels, growers are able to eliminate deep wheel tracks and soil compaction that occurs with traditional pivot systems.
“Our purpose at Teeter Irrigation is to make every drop of water count,” said Monty Teeter, CEO of Teeter Irrigation. “All of our livelihoods depend on water, so we need to implement a plan to help conserve it. Dragon-Line can help fulfill that need.”
Originally patented by T-L Irrigation Company, Netafim is the exclusive provider of drip irrigation technology for the PMDI system, and holds the North American rights to commercialize the system as part of its comprehensive drip irrigation system offering. Dragon-Line is a trademarked term for a system developed by Teeter Irrigation that utilizes the patented PMDI process and technology.
“We’re thrilled to see Netafim’s precision mobile drip irrigation technology recognized as one of the top products of the year, and we value our partnership with Teeter Irrigation to drive further adoption of the yield boosting, water-efficient system among growers nationwide,” said Zeev Barylka, Director of Marketing at Netafim USA. “PMDI enables growers with center pivot systems to immediately benefit from the documented efficiencies of a Netafim drip irrigation system.”
Eliminate evaporation and wind drift
T-L’s patented technology has successfully married center pivot technology with drip irrigation. PMDI™ consists of in-line drip hoses spaced at 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.
Improve water efficiency
With the drip line design, you eliminate evaporation and wind drift associated with traditional sprinklers because wind will not effect it as it applies the 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.
Dry whill tracks
n 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. 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 sytem.
In effect, PMDI™ technology combines the lower cost of center pivot irrigation with the proven efficency of drip irrigation for total water efficiency that approaches 95%.
