Deep Root Irrigation wins World Ag Expo top ten Product Award The all-new DRI system from Deep Root Irrigation LLC saves up to 50% water use compared to surface irrigation. There's no need to get a new emitter--this one attaches to the one you already have, and has multiple advances including: weed growth reduction, evaporation and run-off reduction, promotion of downward root growth, and energy cost reduction. In addition to saving money, water, and energy, the DRI system is durable, lightweight and is able to be installed quickly. The DRI system is designed especially for large agricultural applications, vineyard and tree crops, in particular. With limited water budgets and increasing future demands on crop production, the DRI system offers farmers a solution for the persisting water problem.
