I bet Ken would have something to say about tillage and soil structure ...
! Not sure but how best to re-incorporate organic material into the soil
might depend on soil history, climate, and what material we're looking at.
Sometimes sheet composting or compost mulching may work better. Maybe a
roll of the dice. Soil science is science, but the growing is still an art,
isn't it?

I see fields around us plowed, disced, harrowed, hilled, and cultivated,
and then left bare all winter. Then spring winds carry the dust to the next
state. No wonder they have to spend so much on irrigation. No wonder I see
For Sale signs, 80 acres, 500 acres.
