Evaporation cooling of vineyards
Effective crop cooling of vineyards was obtained with the use of small amounts of water, intermittently applied through overhead sprinklers. The light sprinkling cooled the air, raised the humidity, and cooled the plants. Sprinklers functioning on 3-minute on and 15-minute off periods cooled the air by 7 to 10 degrees and raised the humidity 10 to 20 per cent. Plant temperatures were reduced 15 to 25 degrees. The cost of this operation was minimal. The true potential is still to be explored.
