First you need to decide what you want to plant. You should have a county service that will check your soil and tell you what you need to add, contact them for a soil sample kit, with this you take samples of the soil and send it in and the report back with recomended amounts to add. I you have a farmers co-op type store in the area they can provide good info. Do an internet search on " food plots" and you will get a ton of info.
