Should/can ACT be applied with the tillage, such as
being incorporated, or after the tillage?  Of course, the idea is
that tillage become unnecessary with enough ACT applications, but
this mostly applies to the first couple of years or so.

If there is a compaction zone that needs to be broken open, and there is little biology in your soil to be damaged by tilling, then add the AACT with the tillage event. 

Often tillage works because it allows oxygen to move into the soil, lets roots start to grow again, deeper into the soil.  To maintain soil structure, the organisms need to be added into the soil, so use the AACT to get the organisms into the soil.

What specific herbicides are detrimental to aerobic microbes? 

Not all have been tested.

Atrazine? 

That's a better bactericide than herbicide

Alachlor? 

The little data I've seen, and as I recall, this is affects protozoa more than anything else.

Are soil-based herbicides worse than post

application herbicides? 


Can't generalize that way.

And, I'm
guessing that mixing the ACT and the herbicides together would not be
a good thing?


That's correct.  Add the AACT AFTER the herbicides, so you can resuscitate any organisms killed by the herbicide. 

Try to figure out why you have the weeds growing, and do what is needed to change conditions in the soil so that the weeds aren't not helped, and no longer can out-compete the plants you want growing.
