The only non chemical ways of killing Johnson Grass I have seen are to
clip it, hoe it or plow it every two weeks, turn hogs in on it in the winter
or graze it for two years with cattle. You will still have seedling problems
for several years. I have cleaned up Johnson Grass in one summer by
repeated plowing with sweeps. Rather expensive but it works, You have
to make it use up all it reserves and then it won't make it thru the winter.
Good luck
