Precision Mobile Drip Irrigation (PMDI™)

RETROFITTING CENTER PIVOTS FOR DRIP IRRIGATION

The patented technology of Precision Mobile Drip Irrigation (PMDI) combines the efficiency of surface drip irrigation with the flexibility of center pivot and linear move irrigation systems.

While conventional center pivot and linear move irrigation water application packages are efficient and provide many different options for distributing water, PMDI technology provides increased system application efficiency through precision drip irrigation with the slow methodical release of water and nutrients directly to the soil area for optimal plant growth.

How Does PMDI Work?

PMDI consists of Netafim’s DripNet PC™ drip line which is attached to the end of a center pivot or linear move irrigation system’s rigid or flexible drop and/or a manifold (recommended) – whichever method is best for the crop being irrigated.

The dripline is dragged through the crop by the center pivot or linear move system. As the dripline is pulled behind the system, the emitters deliver a uniform water pattern across the entire irrigated area. The water is applied directly to the soil surface significantly reducing inefficiencies due to surface area and wind drift. This allows deeper percolation to the plant’s root zone.

Drip irrigation precision, accuracy and flexibility combined with pivot system mobility

Simple: Uses minimal components and retrofits to any pivot int the field. User-friendly, simple to design, install and maintain.
Reliable: Uses proven, high-quality Netafim products from the global leader in drip irrigation systems. PMDI has a lengthy warranty to reduce risk.
Affordable: Requires a low investment and just a fraction of the cost of a subsurface drip system for an attractive return on investment.
Operational Efficiencies: Water savings of up to 20% - 30%.

Product Advantages

Potential for 20-30% water savings
Can be used on either tall or short crops
