Jay Harmon, with the agricultural and bioengineering department at Iowa State University, offered 10 steps to managing odor during an environmental seminar. 1) Siting Decisions, the distance to nearby dwellings, the size of the pork production facility and the exposure angles – from the facility to a residence – must be taken into account. 2) Manure Handling, injecting manure can reduce odor 50-75% compared to broadcasting. 3) Dietary manipulation, Harmon feels this is one of the easiest options to implement for reducing odors. Cutting crude protein levels and bumping crystalline amino acids can reduce odors 20%, he says. 4) Cover manure storage, whether permeable (straw, cornstalks, geotextiles) or impermeable (high-density polyethylene or HDPE), covers help prevent gases from escaping. 5) Visual barriers and eye
\nappeal, “Well kept .sites get fewer complaints,” Harmon relates. “It serves as a reflection on the overall management
\nof the site.” 6) Pit ventilation, the more odorous air comes from the pit, contributing more than half of the total odor during critical periods. 7) Biofilters, drawing exhaust air through a biofilter bed can reduce odor, ammonia, hydrogen sulfide and dust. 8) Vegetative environmental buffers, A properly designed vegetative filter helps lift and mix odorous gases. 9) Chimneys, these relatively low-cost design features promote air mixing and reduce the noise of the ventilation system. 10) Other odor deterrents: aeration, barriers, biocurtains, digestion, and oil sprinkling.<\/p>\n","protected":false},"excerpt":{"rendered":"
