Abstract

Dairies utilize copper sulfate
(CuSO4) foot baths to control hoof
infections. Typical solutions are 5 or
10% CuSO4 (pH ~6), equal to 12,500
or 25,000 ppm Cu, respectively.
When spent, hoof bath solutions are
usually disposed of in waste lagoons
and subsequently utilized for irrigation. In the Magic Valley, this practice
appears to be causing soil Cu concentrations to increase. The goal of
our research was to use local waste
products to sequester Cu from a
simulated hoof bath solution and to
use waste products to adsorb excessive Cu from Cu-affected soils.
