Recent studies at Penn State University demonstrate that vegetative buffers can significantly reduce odors, dust and other factors impacting the immediate environment around poultry farms, according to the Poultry Science Association.
 
Findings
include: dust reduction of up to 67% from a 5-row tree buffer; odor reduction of 46% to 54% from a 50-tree vegetative buffer; and the trapping of ammonia emissions with a variety of species. Other positive outcomes of the study were vegetation’s effectiveness in reducing Infectious Bronchitis transmission and its role in cutting energy costs by acting as snow fences and providing shade.
 
The study was funded by grants from the USDA Natural Resources Conservation Service and the Pennsylvania Department of Agriculture.
