For the modern-day dairy farm, the control of on-farm odors is more important than ever since people without a rural background are residing in the countryside and many do not understand or have tolerance or manure-based odors. Land application of liquid manure, especially if it has been stored for a period, in close proximity to neighbors, can be especially problematic. Management strategies exist in order to mitigate odor for both on-farm handling and land application. Land application strategies such as injection, can be used to apply manure in a way that reduces the exposure and/or release of manure-derived odorous compounds.
