ABSTRACT:
A conservation tillage attachment for a seed planting unit that functions to cut and clear away prior crop residue, fracture the soil ahead of the seed trench opener, and form a trench for the deposit of dry or liquid fertilizer offset from and parallel to the later formed seed trench. The attachment includes a single disk blade disposed forward of the seed trench forming unit. The single disk blade is disposed at an angle of approximately 5.degree. from the line defining the direction of travel of the seed planting implement. The attachment includes a selectively adjustable down force structure and a selectively adjustable depth control mechanism.
