I have a small area about 1/2 acre surrounded by a nice plot ofAlpha Feast - It is doing great and being used regularly - I would like to plant this 1/2 acre in the middle with something that does not require lots of soild prep - I know you get what you put into it - but I do not have the time needed to do it right - I can hit it with my ATV disc but this doesn't do much on the hard sod packed prairethat I have recenlty mowed to the ground. Can anyone recommend something to plant in this area? Somethignthat does not require a great seed bed - but will grow in the exposed area my disc will create - I have sprayed the area with arrest to remove the grasses and would like to plant something in there this fall -

Thanks
Mike
