Abstract

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 foot
baths are washed out of dairy
barns and into wastewater lagoons.
The addition of CuSO4
baths has been reported to increase
Cu concentration significantly
in manure slurry from 4.8
g/1000 L to 88.6 g/1000 L (Miner
Institute, New York). 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.
