Abstract
A process for applying particles to a geographic region. The process involves flying a balloon over the region. The balloon carries a nozzle with a pipe communicating the nozzle with a ground supply of air and a source of particles. A mixture of air and particles can be forced up the pipe to the nozzle. The particles are then discharged over the region according to a pre-determined pattern. The process permits the accurate measured application of fertilizers and the like to a forest region.
