Air-emission study: Flushing beats scraping

Flushing of free-stall alleys was twice as effective as scraping at reducing smog-forming emissions from free-stall barns. According to a University of California-Davis study, alleys flushed six times a day had the lowest emission levels, followed by flushing three times a day and scraping three times a day. Alleys that saw no manure removal resulted in the highest levels of smog-forming gases.
