A three step process being used to determine the best technologies for reducing odors from curtain-sided, deep-pit swine finishing barns has been funded. The planned three-step process to research and develop economic, viable and capable dor control systems for Minnesota curtain-sided, deep-pit finishing barns appears to be progressing well, The initial screening is partially completed and five different technologies are in the early implementation stge. Cooperators are coming on board and learning their part of the research. The fast track plan to implement the most promising systems seems to be a reasonable situation and will provide longer term solutions with reasonable data to compare more systems for the unique situaton in Minnesota.
