Manure Storage & Handling—Aeration Overview, Daniel S. Andersen, Jay D. Harmon, Steven J. Hoff, Angela M. Rieck-Hinz Sep 2014

Manure Storage & Handling—Aeration Overview, Daniel S. Andersen, Jay D. Harmon, Steven J. Hoff, Angela M. Rieck-Hinz

Agriculture and Environment Extension Publications

Aeration is the process of mixing air into the manure to promote the growth of aerobic bacteria. Oxygen must be supplied either naturally, mechanically through mixing, or using oxygen diffusion systems. This technology can provide dramatic odor reduction from livestock waste management facilities, but has not found frequent application in agriculture due to intensive energy use and resulting added utility costs.
