Dangerous levels of hydrogen sulfide (H2S) gas released from gypsum-bedding-laden dairy manure storages have imposed risks to animal and human health, as demonstrated both on-farm and in bench scale studies (Fabian-Wheeler et al., 2017; Hile, 2016). Gypsum bedding is popular with some producers for advantages to cow comfort and health along with agronomic benefits. This project demonstrated the effect of iron oxide (FeO2) as a promising additive to dairy manure storages on mitigating H2S releases and odor.
