Abstract: An assembly and method for sequestrating carbon into a soil by grinding a crop waste into a ground material and converting the ground material into a plurality of pellets. The pellets are passed into the soil with a tine assembly or a trenching assembly. The tine assembly has a hollow, elongated body movable between a retracted position wherein a second end is spaced above the soil and an extended position wherein the second end is positioned a distance below the surface of the soil. A gate is pivotally connected to the second end of the elongated body to be movable between a closed position, wherein the gate retains the pellets in the elongated body, and an open position, wherein the gate is positioned away from the second end of the elongated body to permit passage of the pellets from the bore and into the soil.
