✦ Synopsis

A fluorescent tracer was used to study droplet deposition gradients in a wheat crop. Droplets were generated on a free-draining artificial target placed at different heights within the growing crop. Gradients downwind of the target were determined from deposits washed from plant samples.

Deposits were detected to greater distances the higher the target within the crop; with the target at the level of the ears deposits were found to 16 m. When droplets were generated below the canopy their movement was obstructed and deposits were seldom detected beyond 3 m. With few exceptions gradients were significant linear regressions of log deposit on linear distance.
