This study was conducted to test the effectiveness of a sponsor's fertilizer on the phytotoxicity that is a result of dog urine. Kentucky bluegrass, fine fescue, and perennial ryegrass received dog urine then treatment of the test fertilizer, industry-standard or nothing. Data was collected on the rate of germination, root and shoot growth rate, and recovery/survival rate. The results of the study concluded that both of the fertilizers tested failed to provide complete protection from the phytotoxic effects occurring after the addition of dog urine. 3 weeks into the trial no plots had living leaf tissues left. The perennial ryegrass treated with Rothsay fertilizer appeared to slow down the phytotoxic effects and somewhat recovered 6 weeks post-treatment.
