A seeding system for seeding large and small seeds includes a plurality of dispensing apparatuses mounted on an implement frame each comprising a first furrow opener mounted and a second furrow opener spaced laterally from the first furrow opener. A singulating meter is operative to dispense the large and small seeds through a meter discharge. A first seed conduit is connected to the first furrow opener and the meter discharge, and a second seed conduit is connected to the second furrow opener and the meter discharge. A selector is operative in a large seed mode to maintain the connection of the first seed conduit to the meter discharge while disconnecting the second seed conduit, and the selector is operative in a small seed mode to maintain the connection of the first seed conduit to the meter discharge while connecting the second seed conduit to the meter discharge.

Singulating meter feeding multiple furrow openers

A seed supply system includes a singulating meter with a seed reservoir pressurized to a meter pressure that is in a desired pressure range. A seed supply air stream carries seeds dispensed from a nurse tank to an air release assembly located above the singulating meter. As seeds are metered from the seed reservoir at a rate less than the rate seeds are dispensed from the nurse tank seeds accumulate in the air release assembly. The pressure of the seed supply air stream at the top of the seed column fluctuates and a barrier is operative to resist air flow between the air release assembly and the seed reservoir sufficiently to maintain the meter pressure in the desired meter pressure range. The barrier can be provided for example by an airlock or a column of seed in a drop tube between the air release assembly and the seed reservoir.
