A field study was conducted on an Ocilla loamy coarse sand to determine the leaching characteristics of banded and broadcast applications of bromide and chloride. Bromide and chloride were applied in two treatments to eight plots absent of any crop. One treatment consisted of banding one tracer while broadcasting the other. For the second treatment, the banded and broadcast chemicals were reversed. Lateral and vertical movement was observed and comparisons were made between banded and broadcast tracer applications. Results indicate soil variability, dispersion, and diffusion negated potential banding effects on the solute plume below the root zone.
