ABSTRACT:
A double shoot seed and fertilizer placement unit has a leading shank that cuts a fertilizer trench in the soil, a seed shovel immediately behind but above the lower extremity of the shank to cut one or more seed shelves in the soil above and outboard of the fertilizer trench, a boot behind the shovel that places seeds on the shelf and then drops fertilizer into the fertilizer trench between and below the seeds, and a fertilizer guide member that rides in the fertilizer trench below the fertilizer outlet to maintain the integrity of the trench in preparation for the fertilizer and helps guide the fertilizer down to the bottom of the trench as it emanates from the boot.
