- Vegetative buffers filter and trap dust, odor, and ammonia from poultry house exhaust fans.
- Riparian species slow and buffer roof water and road and barnyard runoff, and filter nutrients and sediments.
- Shelter belts around the farm protect birds from winter winds (“windbreaks”) and buildings, feed bins, access roads, and doors from drifting snow (“living snow fence”).
- During hot weather, shade trees block the solar heat load on barns, reducing energy expenditures.
- Biomass buffers can be used to grow bedding, and pine shavings can be replaced with miscanthus or switchgrass straw, chopped willow, or poplar shavings. Spent litter can be utilized as a renewable, carbon-neutral fuel to replace fossil fuels like propane.
- Screen poultry management activities using buffers composed of attractive trees and shrubs that can also landscape and beautify the barns and farm.
Conservation Practices That Work for Your Farm
- Strategically select and place plants around buildings to divert energy-robbing winds and snow and modify the temperature in the surrounding area.
- Locate vegetative buffers near the ventilation exhaust system to filter ammonia and particulate matter, which carries odor and microorganisms.
- Plant riparian species near barnyards, roof runoff, and drainage ways to control runoff and absorb excess nutrients that can pollute the water.
- Grow bedding materials on the farm for bedding and fuel sources, reducing costs and your carbon footprint.
