Abstract
A double shoot dispensing system including a shank for opening a treatment trench, a seed shovel for creating left and right seed shelves above and on opposite sides of the treatment trench, and a two-piece boot body having a plurality of internal passages defined by assembled left and right halves of the body. A first passage directs the seeds onto the seed shelves, a second passage directs a granular fertilizer treatment into the treatment trench, and first and second tube passages receive first and second tubes delivering additional treatments into the treatment trench. Left and right ducts branch from the first passage so as to guide the deposit of the seeds. The body is constructed of a material having a relatively low mass and a relatively low coefficient of friction, such as polyurethane, polyethylene, nylon, or polyacetal, and is externally shaped so as to taper in a direction of travel.
