How can odors from manure be minimized?

Minimizing odors from manure is essential for effective nutrient management and maintaining good relations with neighbors. Immediate incorporation into the soil is effective because it reduces exposure of the manure to air, which is a primary factor that contributes to odor development. When manure is left exposed, biological processes, including decomposition and the release of volatile organic compounds, occur rapidly, producing strong odors. By incorporating manure into the soil promptly, these processes are significantly reduced, leading to a decrease in odor emissions. Furthermore, incorporation into the soil helps to enhance nutrient availability for plants and reduces the potential for runoff, thus benefiting both the environment and the agriculture operation.

Other methods like covering with plastic can trap gases but may not eliminate the odor at its source. Storing manure for longer periods often leads to greater odor issues as the manure becomes more decomposed and more gases are released. Airing it out in open spaces might briefly diminish the concentration of odors but does not effectively manage the source of those odors in the long term. Immediate incorporation stands out as the most effective practice for reducing odor emissions associated with manure management.
