SPREADING OF PARTICULATE MATERIAL ABSTRACT OF THE INVENTION A pneumatic spreading system for particulate material such as granular fertilizer includes tank and a pair of booms extending outwardly from the tank for transportation across the ground. A pair of parallel belts lie in the same horizontal plane and carry a metered layers of the material out of one end of the tank adjacent the booms for discharge as a curtain of the material at a discharge end of the belt. The booms each include a plurality of pipes with all of the pipes lying side by side in the same horizontal plane and each pipe including two distribution nozzles forming a split pipe arrangement. A manifold for airflow is positioned between the two booms injecting air into each pipe of both booms. Each pipe includes a feed opening into which the material falls from the discharge end. A guide arrangement in the form of a plurality of funnels is provided between the discharge end and the pipes with the funnels formed from side walls and end walls which are shaped to guide the material to the staggered feed openings of the pipes. Additional materials in particulate or liquid form can be applied onto the belt for simultaneous spreading action.
