Abstract
A planting unit for depositing fertilizer and seed in a single pass, double shoot manner includes a rotating disc that cuts a furrow in a planting surface and a trailing seed boot, having a cutting edge, that cuts a vertically and horizontally offset trench in the furrow to form a seed bed in the planting surface. The disc has a mounting frame for mounting the disc to a linkage assembly that is, in turn, coupled to a toolbar mount. The seed boot is also attached to the mounting frame. This common attachment provides a relatively short and compact device without sacrificing fertilizer and seed stratification.
