The adverse effects of wind—chilling of dairy cows, poultry, and other livestock during cold weather, soil erosion and air pollution, scarring of citrus fruits such as lemons, and on fire control—are often economic factors in California agriculture.

Wilbor O. Wilson, Professor of Poultry Husbandry, and Lee Femling, Gerald Henderson, David van Rest, and C. R. Miller, Department of Engineering, University of California, Davis, assisted in the slatted fence windbreak experiments.

Funds for the tests reported were provided, in part, by Tynan and Rogers Mfg. Co., Salinas, California.
