Abstract: A seeder and liquid applicator is adapted for mounting on a sweep-type spreader for use in agricultural seeding and fertilizing operations. The spreader includes a shank for mounting it on an implement. A T-head support is bolted to the spreader shank. The T-head support mounts a T-head which is connected to a seed hose. The seed hose is also connected to a seed source on the implement. A liquid tube is connected to a discharge novel mounted on the liquid tube. The feed hose and the liquid tube are secured to the T-head support and to each other. Seeds are discharged horizontally and laterally from the T-head and liquid fertilizer is discharged rearwardly in line with the direction of travel of the spreader.

Abstract: A marking system for indicating the boundaries of an area that has been treated includes a storage tank for storing the liquid and the foaming agent that is fluidically separated from a foam tube. A mixing control element fluidically connects a compressor to the foam tube and connects the storage tank to the foam tube whereby the ratios and parameters associated with the formation of the marking foam can be varied. The system includes two marking foam dispensing nozzels.
