Abstract: An air fertilizer spreader mounted on a truck chassis, the truck chassis carrying a granular or pulverized fertilizer application machine. Right and left booms swing from a midship position between a truck cab and fertilizer box back towards the rear of the truck chassis. Each boom includes a plurality of boom tubes with deflectors. Rear boom tubes are also provided at the rear of the truck chassis. A screw conveyor carries fertilizer from the fertilizer transport box to an area forward of the fertilizer transport box where the fertilizer falls into opposing metering assemblies for the right and left boom. Air, acting through particle accelerators carries the fertilizer from the metering assembly to the entrance of the boom tubes, and a second particle accelerator provides additional air flow to carry the fertilizer down the length of each of the boom tubes to the point of discharge.
