Abstract: Treatment assemblies and systems including treatment assemblies are provided. One example treatment assembly includes an inlet configured to receive a treatment product, an outlet, and at least one rotatable wheel. The at least one rotatable wheel includes a base having an outer circumferential surface, and tabs extending away from the outer circumferential surface of the base. The tabs define receptacles each configured to receive a portion of the treatment product from the inlet as the wheel rotates. The at least one rotatable wheel is configured to transport the portion of the treatment product from the inlet and deliver the portion of the treatment product to the outlet. The outlet is configured, then, to dispense the portion of the treatment product to a field.
