I have an old cultivator toolbar that I am going to convert over to a liquid fertilizer sidedress toolbar applicator.
Which coulter injection units are best?
FAST in Gilman,IL recommends this Clymer type?
It is a knife, but it also comes with an injection knozzle.
Smooth or wavy coulter?
I plan on using it for conventional till, no-till, & strip-till applications so residue will be an issue.
Are there better units or ways to accomplish it?

I used an AC plow coulter with the thin knife behind it. Worked fine with 32%. I mounted it on front of the planter first to put down 32% off a couple inches from the row which also cut the residue so the trash wheels could part it and not leave it for the planter opener disks to hairpin stems.

I have also used a vintage planter as the side dresser, at 60 inch spacings. And my best corn year, I used flexible drops after my coulter assembly broke the first pass across the field. Got 173.2 bushel corn after poor beans from 111 pounds of N per acre. I believe variety selection was important there too.

Over on New AG Talk crops forum side dressing is discussed a great deal.

I did not use a rippled coulter, I did not want the dirt packing in wet spots.

These work great as long as you don't have any corn stalks to go through.My biggest complaint is getting cobs between the colter and the knife, then it starts dragging. Hope this helps.
