This project aims to optimize water use in irrigated potato crops. An existing center pivot irrigation system will be converted to a mobile drip irrigation system (MDIS) by replacing the sprinklers with drip tubing. The tubing is dragged over the ground by the pivot as it advances. Water is therefore mainly applied to the ground under the canopy, thus limiting water losses through evaporation, drift and water falling between rows. Moreover, it avoids wetting the foliage. Also, the height of water applied per episode is lower, which decreases nitrate leaching and prevents fungicides from being washed off the foliage. The equipment can also be used to irrigate the rotation crop. Although its usefulness remains to be demonstrated under production conditions in Quebec, the MDIS could become a means to improve irrigation efficiency, reduce pesticide use and increase the profitability of the farm.
