  • Patent number: 5271342
    Abstract: A device is provided for injecting fertilizer into soil simultaneous with tilling or plowing the soil. The fertilizer injection device is attached to a shank portion of a plow and includes a distribution conduit which is spaced behind and separated from a point on a soil moving surface of a trailing edge portion of the soil moving tool. Fertilizer is thus more effectively injected into the soil resulting in a high rate of absorption.
