In one aspect, a system for removing blockages present within a delivery conduit of a seeder may include a plurality of delivery conduits, a plurality of flow blocking devices, and a plurality of blockage sensors. A controller may be configured to determine when a blockage is present within a first delivery conduit of the plurality of delivery conduits based on measurement signals received from the plurality of blockage sensors. The controller may be further configured to control the flow blocking devices to occlude the flow of air through the other delivery conduits of the plurality of delivery conduits such that an air pressure in the first delivery conduit is increased.

A material conveying system, comprising: one or more material sources for providing material to be transferred; one or more destination locations for receiving material from the one or more material sources, wherein each destination location has a destination material inlet valve and a destination vacuum valve; one or more material conveying tubes each configured to connect a source to one or more destination locations; a vacuum pump operatively connected to each of the destination vacuum valves via one or more vacuum source tubes, and wherein the vacuum pump is operatively connected to one or more of the material sources through the one or more vacuum source tubes and respective destination vacuum valves, the one or more destination locations and the one or more material conveyor tubes; a first sensor disposed on or near each destination vacuum valve; a second sensor disposed on or near each material inlet valve; a third sensor disposed on or near a vacuum outlet of the vacuum pump; a programmable system controller connected, via wires or wirelessly, to each component of the material conveying system including the one or more material sources, the one or more destination locations, the vacuum pump and to each of the first, second and third sensors; wherein the programmable controller is configured to determine first baseline readings from each of the first, second and/or third sensors while the system is operating but prior to any material being conveyed through the system.
