I'm just wondering, that even using this method, why bother using any costly chemical sprays at all?
If the rye was just rolled flat and not killed by some method it would spring back up and compete with the cash crop just as they were germinating. The cost of the "costly" herbicide application is just $15.00 per acre which is much less then the cost of turn plowing or rotovating.
The rolling and spraying method also leaves the root mat in place and the dieing rye stems in place to prevent erosion and retard weed infestation and moisture evaporation. Think of it as applying a two inch layer of mulch at the rate of two acres a minute.
I'm still researching so haven't formed my final opinion as of yet. I also have seen presentations where cover crops were rotovated in on organic farms and others where cattle were mob grazed for one to three days to remove the bulk of a cover crop while processing some of it into manure. Weight gains of three pounds per day per calf were reported.
I personally know some farmers that became organic certified for a few years but switched back due to the tillage costs and resultant erosion it allowed.

Yep, that's the way.
