ABSTRACT:
An improved fertilizer system for use in conjunction with a sweep blade comprises a pipe and a structural channel. The pipe carries liquid fertilizer along each blade and is protected along the blade by the channel. The channel is bolted or otherwise attached to the blade to form a box section in which the pipe is run so that the blade, pipe and channel are rigidly joined. Apertures are drilled through the channel and radially into the pipe at appropriate intervals along the blade to provide a suitable distribution of fertilizer into the soil as the sweep blade moves through the soil.
