A method of inhibiting dry material clogs in a work vehicle having an air boom assembly includes moving the work vehicle at a vehicle speed along a ground surface, moving dry material from a holding tank onto a conveyor, and operating the conveyor at a conveyor speed, the conveyor speed being at least partially dependent upon the vehicle speed, moving material from the conveyor into a boom assembly with a blower, dispensing the dry material onto the ground surface through a plurality of nozzles of the boom assembly, and comparing the conveyor speed to a maximum acceptable conveyor speed. If the conveyor speed is greater than the maximum acceptable conveyor speed, the method includes performing at least one of the following: alerting the operator that the conveyor speed is greater than the maximum acceptable speed, and reducing the vehicle speed to thereby reduce the speed of the conveyor.
