Some offline comments indicated my suggestion of steam as an ideal
herbicide was funny or a joke.
Maybe funny, indeed, but I am serious. There are several devices which
use steam to prepare a seed bed.
In my memory from years ago--I mean decades--is a picture in National
Geographic magazine of Amish farmers in the Midwest using an ancient
steam tractor. They would drive the tractor to the field, and then
connect a large pipe from the tractor's boiler to a metal box about 4
feet by 6 feet by 6 inches high. Tamp the box around a patch of
carefully prepared planting soil. An hour or so of steam from the
tractor's boiler would completely sterilize the upper few inches of a
good sized seed bed. Non toxic yet very effective.
