ABSTRACT:
Apparatus for injecting granular material such as nematicide in soil comprises a frame carrying a plurality of tines for opening vertical slits in the soil when dragged through the soil by movement of the frame. Each tine has a conduit for delivering granular material to the rear of the tine, and each tine also has an outlet means connected to the conduit of the tine. Each outlet means has one or more outlet openings for directing the granular material rearwardly of the tine. Each outlet means is shaped for guiding granular material in a flow path or flow paths leading from the conduit to the one or a group of outlet openings for directing the granular material rearwardly predominantly in a vertically dispersed distribution. Preferably each outlet means has an upper outlet opening directing granular material in an upward direction rearwardly of the tine, a lower outlet opening directing granular material in a downward direction rearwardly of the tine, and a further outlet opening directed in a direction intermediate the directions of the upper and lower openings. Preferably each outlet means includes a chamber disposed in the said flow path or flow paths, the chamber having a curved wall arranged to guide the granular material along the said flow path or flow paths.
