A novel coulter, as well as a novel tillage tool including that novel coulter, are provided herein. The coulter includes a circular body having a peripheral edge, a centre portion, and a radius. A plurality of waves are formed in the body, each wave including a curved crest and an adjacent curved valley defining a wave width at the peripheral edge which is disposed perpendicular to the plane of the circular body. Each crest and adjacent valley extend back from the peripheral edge in respective adjacent lines which are disposed at a predetermined acute angle with respect to the radius. The coulter is rotatably attachable to an implement frame at a centre portion such that a leading peripheral edge of the coulter rotates in a downward direction as it enters soil, thereby positioning the lines of each crest and valley to enter the soil at a nearly vertical orientation, whereby compaction of the soil is minimized. The tillage tool includes an implement frame for movement in a direction of travel over soil to be tilled. The tillage tool is provided with the above-identified soil-engaging coulter which is operably attached to the frame and is positioned forward of a no-till implement which is also operably attached to the frame.
