In my part of Wisconsin, no-till is just getting to be common in the
family farm setting. So things move slow. Like I said, it's not that
they're ignorant of it, they're just chosing not to use it in some
cases.

In northern climes there often isn't enough useful rotting time for low or
no till to be effective. Depending on the next crop, it is often best to
turn it under.

Also, those areas typically do not have the moisture conservation
pressure and wind erosion issues to the extent we have, both of which
are addressed by low/no-till...
