Minimal Pruning

Creator:: Price, Steve, Lombard, Porter, and Watson, Barney
Abstract:: Traditional vineyard practices in Oregon are labor intensive and require large pools of available labor for pruning, shoot positioning, and harvest. A mechanized system of grape growing has been developed in Australia to eliminate almost all of the handwork involved with grape production. The cornerstone of this system is minimal...
