ABSTRACT:
A liquid fertilizer injection system is provided that includes a single coulter blade mounted on a support arm extending from a bracket which is adapted to be pivotally coupled to an attachment apparatus which attaches the system to a propulsion means. A spray arm is adapted at one end is attached to the support arm and is adjustable in the up and down direction by means of a slot bracket. A second end of the spray arm is attached to a spray nozzle which is adapted to receive a flexible tube. The flexible tube transfers, to the nozzle, liquid fertilizer, under pressure, from a liquid reservoir via a pump. The system further includes a tension spring assembly which provides a down-force, determined by the user, to the coulter assembly, while isolating the system from the propulsion means, thereby preventing lifting of a planter or seeder to which the system is connected off of the ground.
