Abstract
Disc openers () for use with an air seeder () are configured for seeding and fertilizing a field (G). The opener () broadly includes a coulter disc (), a seed boot (), and a fertilizer injector wing (). The fertilizer injector wing () is configured for fixed attachment to the seed boot () and broadly includes a body (), including an angled outboard portion (), a toxic fertilizer injector (), and a non-toxic fertilizer injector (). The opener () with the fertilizer injector wing () 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 (and), 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).
