LEACHING CHARACTERISTICS OF BANDED AND BROADCAST INORGANIC TRACERS

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