As mentioned....It really depends upon the soil...and what you are planting...With grasses, it will work..just like planting your lawn...with clover..no need...just cut area close, and plant...with soybeans, disk, broadcast beans and disk lightly again....

PS....If you can supply more details I should be able to help further...I used to cover VA for John Deere...so I know a little about the area and farming...
