Landscaping can reduce downwind concentration of housing dust
and odors, beyond the property line, by trapping and treating particles
and gas emissions. Trees and shrubs act as biofilters for fine
particles and odorous compounds that are attached to them. By landscaping
with both a treeline and a row of shrubs, particles at various
heights within a plume can be adsorbed. To maximize adsorption,
landscape materials with large surface areas are recommended. Trees
and shrubs places around the facility should not impede building
ventilation and are often located on the property lines.
Costs associated with landscaping will vary
depending on selected trees and shrubs, and on perimeter size. Estimates
of a shelterbelt planted around a 3000-head hog facility using "higher" cost
trees ($25 per shrub or tree), calculated as $0.68 per pig for one
year, amortized over 20 years at 5 percent, is just $0.09 per pig.
These costs include maintenance costs. In addition to acting as a
natural filtration system for odors, landscaping has the additional
benefits of being aesthetically pleasing to the eye and of restricting
the view of the operation. So, while documented effectiveness on
emissions is scarce, the value of creating a facility that is pleasant
to the eye cannot be underestimated. Extension Publications
