A rising concern with the application of dairy wastes to agricultural fields is the accumulation of
copper (Cu) in the soil. Copper sulfate (CuSO4) from cattle footbaths is washed out of dairy
barns and into wastewater lagoons. The addition of CuSO4 baths can increase Cu concentration
significantly in manure slurry, from approximately 5.0 grams per 1,000 liters to 90.0 grams per
1,000 liters. The Cu-enriched dairy waste is then applied to agricultural crops, thus raising
concerns about how soils and plants are impacted by these Cu additions.
