"I'm pretty impressed with my PMDI installation with 30 inch spacings. And, while I don't know for sure, since no water is being sprayed into the air I'm guessing efficiency is close to 98 percent."

T-L Irrigation is proud to introduce the latest in irrigation technology. At T-L our motto has always been “The Choice is Simple.” With the simplicity of hydraulics and the continuous movement of a T-L we have the best water application you can get. T-L has gone one step further in combining the simplicity of hydraulics.This new application is called PMDI(TM) (Precision Mobile Drip Irrigation).

T-L’s newly patented technology has successfully married center pivot technology with drip irrigation. PMDI(TM) consists of in line drip hoses spaced at 30″ or 60″ between lines being dragged through various crops by a center pivot or linear move irrigation system.

PMDI(TM) combines the efficiency of surface drip irrigation (95%) with the flexibility and economics of center pivot irrigation. Comparing corn irrigated with PMDI from a 300 GPM well, to fields receiving double or more that amount of water, he estimates the yields will be about the same.

“I’m pretty impressed with my PMDI installation with 30 inch spacings. And, while I don’t know for sure, since no water is being sprayed into the air I’m guessing efficiency is close to 98 percent,” Danny McMillan, Garden City, Kansas, remarks.

Comparing his corn watered with it from a 300 gallon a minute well to fields where the systems are pumping double or more that amount of water, he thinks the yields will be right up there with corn irrigated from his best well.

“The PMDI system costs a little bit more than a standard nozzle T-L package,” he says, “yet I think it will pay off after just a couple of seasons.”

McMillan also says he noticed all through the growing season exceptional uniformity of the corn crop with the PMDI system. “Efficiency is what it’s all about,” McMillan sums up. “You need to utilize every drop of water that you pump out of the ground, and I feel with PMDI we’re doing just that.”
