Thanks much for these links. I will avail myself of the opportunioty to d/l 
these works.
I need to see photos and diagrams but am still beginning to get the Keyline 
concept.

I used my own Yeomans plow
(http://photos1.blogger.com/blogger2/1972/907063824599259/1600/Yeomans-Plow-2.jpg)
this Spring and did it ever bring up some hefty chunks of hard dirt
to the surface to become homogenized with the upper layers. This is a tillage 
tool to use as
frequently as soil conditions permit.

Obvious question: How is Yeomans plowing accomplished on steep slopes along 
contours?
Only when therer is enough flat ground for the tractor to traverse safely? Or 
are teams of
big draft mountain goats used :-)
