N2  - An hydrometer and a titrimetric colour change method were compared as 2 on-farm tests for assessing the strength of zinc sulfate in footbaths used for the control of footrot in sheep. Contamination of zinc sulfate solutions with soil, water, and sheep faeces and urine reduced initial concentrations by up to 33%; however, zinc sulfate concentration could be still assessed by the 2 methods. The hydrometer was found to be the most practical method for on-farm use.
