Abstract: Odorous gas emissions from swine production have been a concern for neighbors and communities near livestock farms. Manure storage is one of the main sources of gaseous emissions. Manure additive products are marketed as a simple solution to this environmental challenge. Manure additives are user-friendly for producers and can be applied (e.g., periodically poured into manure) without changing the current manure storage structure. Little scientific data exist on how these products perform in mitigating gaseous… Show more

“…Stage 1-biochar is surficially applied to stored manure, where it mitigates the perennial environmental problem, i.e., gaseous emissions of odor and air pollutants [21][22][23][24][25][26][27]. Biochar fits a need since many marketed manure additives have not been proven effective [28]. Stage 2-the manure-biochar mixture is applied to farmed land as a value-added fertilizer, with the potential to improve soil OM and plant-available nutrients (NO 3 − , NH 4 + , P, and K) while lowering the risk of nutrient leaching loss [20].…”

“…Small doses of manure additives can be easily applied to manure without changes to the current waste management structures. However, in recent research, 12 commercial manure additives did not show significant impacts on the targeted gases in controlled side-by-side trials [5,6]. Thus, there is still a need to develop and test manure additives that are adaptable to current animal farming systems.…”

“…Researchers have shown the effective H 2 S and NH 3 reduction with calcium hydroxide, sodium nitrate, and hydrogen peroxide treatments at the lab scales, but the potential of scaling up to real farm application was limited by the economics [17][18][19]. A recent comprehensive evaluation of marketed manure additive products for controlling odor emissions and nutrient losses did not show statistically significant mitigation of H 2 S and NH 3 [20]. Thus, there is a need to mitigate the safety concerns and gaseous emissions representing the loss of nutrients and manure value as a fertilizer.…”
