Abstract
A liquid fertilizer applicator is provided, designed to be pulled by a motive power source, for use in a variety of soil and tillage conditions. It includes a disc-shaped coulter and an associated applicator knife mounted in trailing relation to the coulter, with a feed tube fixed to the rear of the knife. The leading edge of the arcuate knife conforms to and lies in close proximity to the outer periphery of the coulter disc. An alternative arrangement includes a knife with an angled lower facing edge and a heel extension to protect the feed tube opening.
