The Spoke Injector consists of a wheel with 12 hollow stainless steel spokes which penetrate the soil as the wheel turns.
Liquid fertilizer is nested at 8" intervals, 3 1/2" below the soil. The row widths can be adapted to your crop requirements.

Liquid fertilizer, at low pressure, is supplied to each spoke through the wheel hubs. A rotary valve, within the hub, meters an accurate amount of fertilizer to each spoke.
A spring loaded shank provides adequate pressure on each wheel to ensure optimum penetration. |
