Abstract
An ammonia knife assembly is mounted onto a toolbar and is moved across a field to apply ammonia into the bottom of a trench. The ammonia knife assembly includes a knife for piercing the ground and creating the trench, an ammonia supply tube, and a horizontal shield attached to the knife. The shield has a rounded portion extending forwardly from the leading edge and two side portions extending outwardly from the sides of the knife for deflecting any dirt particles that may be thrown upwardly and outwardly from the leading edge of the knife as it pierces the ground.
