A ground engaging agricultural blade, coulter, or disc having a central opening adapted to be attached to an implement for rotation about a substantially horizontal axis of rotation; the coulter or disc have an outer periphery; and plurality of step plane notches disposed in the outer periphery. The blade can be used with a hub disposed around the central opening or a spacer spool on a shaft extending through the central openings of adjacent blades, the spacer spools extending radially outwardly by a distance.

An agricultural implement with various sensors for measuring properties of soil while performing normal planting or other operations. The sensors include a plurality of flexible tine assemblies used as electrodes for measuring soil EC. The flexible tine assemblies each have a lower end arranged to contact soil, and an upper end with a coil spring configuration attached to an electrically isolated support structure. The coil spring configuration allows the flexible tine to flex rearwardly to shed residue and clear obstructions. The flexible tine is arranged behind a soil engaging tool, such as an opener assembly or a residue clearing device, with the lower end contacting soil exposed by the soil engaging tool. Other soil sensors on the implement include sensor modules positioned in furrows behind the opener assemblies, and non-contact optical sensors arranged to measure reflectance of soil exposed by the opener assemblies.

Methods, systems and apparatuses for applying a sheet of film material to the ground by utilizing first and second double disk openers to create first and second grooves in the ground and inserting the sheet into the grooves by use of a pair of press wheels which travel behind the disk openers and force the sheet into the grooves. Use of the disk openers accommodates a method of applying the sheet to planted seeds in non-tilled, frozen and/or near frozen soil conditions for increased crop yields.

A method of manufacturing an agricultural tillage disk blade includes providing a substantially circular-shaped disk body with an outer peripheral edge and a central opening that defines a rotation axis, the outer body being disposed within a first plane. A plurality of waves is formed in a predetermined pattern in the outer peripheral edge of the disk body, and the outer peripheral edge is sharpened to form a plurality of teeth such that at least a portion of the sharpened outer peripheral edge is disposed within a second plane that is parallel to the first plane and substantially perpendicular to the rotation axis. The method also includes machining a plurality of relief portions in each of the plurality of waves at a location radially inward of the plurality of teeth, and heat treating the disk body after the sharpening and machining steps.
