Abstract
A knife applicator is provided for a tillage implement to apply liquid fertilizer into the ground. The knife applicator is formed as a base member with a point member welded to the forward edge thereof to create a furrow when moved through the ground. A fertilizer tube is positioned rearwardly of the base member to deliver liquid fertilizer into the opened furrow. The point member is formed in a rounded tip that presents a smooth rounded surface that fractures and lifts the soil effectively to create the opened furrow. A raised member on the point member assists in the lifting of soil from the furrow being opened while creating only a minimal disturbance to the surface of the ground. A wedge member having a lowered operative edge seals the opened furrow to prevent the liquid fertilizer from escaping into the air.
