What are you using for opening a trench?...........knife?  disk blade?  Brand?

How tall before you DON't do any more------6-8 inches?? 

30-inch rows.

If history holds, it will probably wet in May..........so I am guessing that disk blades will be best.........but would like to hear experiences.

Seems that the primary concern is not keeping the slurry in the trench, and having it run onto the corn, and burn it...........??

It would be nice to be able to come in behind the application in a few hours, and row cultivate-------but that would require making an assumption that the weather would cooperate............a little chancey at best.

Thanks.
