ABSTRACT:
A minimum tillage planting system configured to facilitate a wider, enhanced seedbed in a variety of soil conditions, while maintaining nominal surface disturbance. The present invention may further be configured to provide intercrop planting, renovating, and/or fertilizing. The preferred embodiment of the present invention contemplates a planter/fertilizer including a ripping point configured to penetrate a predetermined depth into the soil or sod, the ripping point designed to facilitate a splitting and lifting of the ground cover, widening same, and lifting same to a prominent head, wherein first and second coulters, situated above and about the ripping point, are configured to independently engage and cut first and second sides of the lifted ground cover, and then cutting the lifted ground cover a second time as the coulters rotate, chopping the lifted ground cover and displacing same from the furrow, while depositing fine chopped tilth into the seedbed, providing a planted region with an enhanced seedbed and furrow with nominal surface disturbance. An alternative embodiment contemplates a system wherein there is provided a foot shank having a lower slicing tip and a vertical supporting edge, and a vertical slicing coulter situated in frontal, off-aligned fashion with the vertical edge of the foot shank. A second, scalloped coulter, situated at about twenty-one degrees relative to the side of the vertical supporting edge of the foot shank is provided to sever lifted ground cover in the vicinity of the foot shank, again providing a wider seedbed with nominal surface disturbance, and a clean, wider furrow.
