COMBINED VERTICAL AND HORIZONTAL TILLAGE WITH HARDPAN PENETRATION

摘要

An exemplary best mode embodiment and various alternative embodiments are shown for combining horizontal and vertical tillage to solve both weed control and penetration of compaction layer. In one exemplary embodiment a large colter or tine is disposed behind a plow, sweep, concave disc, or other horizontal tillage implement to slice the soil to penetrate any compaction created by the implement. In another exemplary embodiment, a colter with lateral blades penetrates a surface compaction layer, chops crop residue and hoes and levels the soil all in one pass with one implement. We have discovered that a deeper-penetrating tailing ground slicing implement behind a horizontal tillage device results in full root depth for a stronger crop and better yields with normally deep-rooted crops such as corn and the like.
