6.2 Windbreaks for Odor Control

Windbreaks can reduce odors from livestock and sewage facilities and other odor-producing sources. Plant buffers with a mixture of tall trees and shrubs, particularly conifers, close to the odor source. Strive for 50 to 65 percent density. A windbreak system around the perimeter is often desirable. See 6.3 for additional guidelines.
