Impact sprinklers are the most common type of irrigation system used in kiwifruit vineyards in the Pacific Northwest. They can be placed over or under the canopy. Impact systems work well if the canopies aren't in the way, but they tend to use more water than drip or minisprinkler systems.
Overhead sprinklers are best for frost protection. Some growers use a T assembly on the sprinkler riser to switch from over-vine sprinklers to under-vine sprinklers. They use the over-vine positions for frost protection (shoots in the spring, fruit in the fall) and switch to the under-vine position in summer. (Note that only fuzzy kiwifruit are sensitive to fall frosts, because hardy kiwifruit mature earlier.)
Place under-vine sprinklers between vines in order to reduce impact on the trunk.
