A pneumatic agricultural particulate material delivery system for delivering agricultural particulate material to a growing medium is disclosed. The delivery system includes a particulate material supply chamber, a furrow opening device configured to create a furrow in the growing medium, a plurality of tubes providing an interior passage extending from the particulate material supply chamber to an outlet proximate the furrow opening device and a pneumatic pressure source pneumatically coupled to the interior passage to supply pressurized air to the interior passage to move material within the interior passage. The plurality of tubes includes an end-most material delivery tube providing the outlet. The end-most material delivery tube includes a plurality of openings extending therethrough in communication with the interior passage. In one exemplary embodiment, the plurality of openings are louvered so as to extend at a downward angle towards the outlet. In other exemplary embodiment, the furrow opening device includes at least one disk having an upper circumferential edge and a lower circumferential edge, wherein at least one of the plurality of openings extends below the upper circumferential edge.
