Abstract: A furrow opener is operable as part of a nonsingulating air seeder and includes a rotatable disc to open a furrow. The opener also includes a vented seed catch pan positioned adjacent one side of the disc. The catch pan is operably coupled to a seed conduit of the air seeder to receive seed in a pressurized air stream from the seed conduit. The catch pan presents a seed inlet configured to receive seed from the seed conduit, a seed outlet positioned to deposit the seed within the furrow, and an elongated chamber extending between the inlet and outlet. The catch pan presents multiple vents spaced between the inlet and outlet, with the vents allowing pressurized air flow to escape from the chamber to ambient without passing through the outlet.

Abstract: Disc openers (14) for use with an air seeder (10) are configured for seeding and fertilizing a field (G). The opener (14b) broadly includes a coulter disc (20), a seed boot (24), and a fertilizer injector wing (26). The fertilizer injector wing (26) is configured for fixed attachment to the seed boot (24) and broadly includes a body (48), including an angled outboard portion (56), a toxic fertilizer injector (50), and a non-toxic fertilizer injector (52). The opener (14b) with the fertilizer injector wing (26) is configured to place the seed row (S) and the dedicated fertilizer band (DB) at an optimum geometric positional alignment relative to the seed row (S), in a single, low soil disturbing planting pass without disrupting the seed bed (BS). In alternative wings (300 and 400), the sufficiently safe geometric positioning is accomplished by the force of delivery of the fertilizers (N and P) coupled with an offset angle (OA) defined between a fertilizer injection axis (AF) and a seed outlet axis (AO).

Abstract: Disc openers (14) for use with an air seeder (10), are configured for seeding and fertilizing a field (G). The opener (14b) broadly includes a drawbar assembly (16), a disc assembly (18) including a coulter disc (20) and a gauge wheel (22), a seed boot (24), a fertilizer injector wing (26), a firming wheel assembly (28), and a closing wheel assembly (30). The fertilizer injector wing (26) is configured for fixed attachment to the seed boot (24) and broadly includes a body (48), including an angled outboard portion (56), a toxic fertilizer injector (50), and a non-toxic fertilizer injector (52).
