A soil probe assembly includes a frame member and a wheel rotatably coupled to the frame member. The wheel includes one or more soil probes that, as the wheel rotates against the earth, the weight of the soil probe assembly drives the soil probes into the earth. The wheel is configured to have at least two planar edges such that, as the wheel rolls onto one of the at least two planar edges, a slamming effect occurs due to the planar edge impacting against the ground, thus causing a soil sample to eject from a soil probe located across the wheel from the ground. The ejected soil sample is collected by a collection hamper. The assembly includes a funnel and a carousel such that the funnel is configured to receive and direct the ejected soil sample to the collection hamper, wherein the collection hamper is coupled to the carousel.

A grouser-cage attachment for equipment is an apparatus that imprints troughs into the soil. The apparatus includes a main frame, a roller, and a grouser cage. The main frame connects the roller with a piece of equipment or large machinery such as a skid steer. The roller presses the grouser cage into the soil. The grouser cage further includes a cylindrical frame, a plurality of holes, and a plurality of cleats. The cylindrical frame supports and positions the plurality of cleats around the roller. The cylindrical frame freely rotates around and with the roller. The plurality of holes and the plurality of cleats imprints troughs into the soil. The roller presses the plurality of cleats into the soil.
