ABSTRACT:
The invention comprises an apparatus for the subsurface application of chemicals such as metham sodium in soil. A frame is shown, capable of being pulled across a field, the frame having a plurality of shanks with a plate and a rearwardly discharging wide angle flat spray nozzle mounted at the end of each shank. The plates all lie in a single plane, substantially horizontal to the soil's surface. Structure is provided for delivering the chemical from a reservoir to the nozzles. The chemical is thereby applied in a single pass at a depth of up to 12 inches, and allowed to migrate upward in the soil, thereby achieving application of the chemical in a discrete layer of the soil, without unduly disturbing the soil's surface.
