I prefer to plant brassicas seperate from my clover / chicory. I plant part of the field (25-30%) in brassicas and the rest is left as a perennial clover / chicory plot. If you keep the clover / chicory mowed to handle the broadleaf weeds and spray with Select or Poast to handle the grasses, your clover / chicory plot should last 4 or 5 years easily. Spread 200 lbs per acre 6-28-28 each year if you can afford it & you should have great growth. I typically quit mowing by mid-August to leave lots for the deer to feed on in the fall.
