Soil drench, what gun?

[Turf Troll]

I would like to do soil drench this year from my spray tank which I use a JD-9 to spray,
Does anyone have a unit to put on to insert in ground to do a drench and what pressure would you recommend,

Thanks

Call Mark Cruse at Westheffer (800-362-3110) and ask about the "Chemlance" fertilizer probe. Lightweight aluminum body that adapts easily to the jd-9 gun. Available with or without the drench-cup and splash guard. Also can be easily shortened for those that are "height-challenged".
