I would continue your prep work so that you have a head start for the spring. Make sure to get a soil sample from the plot and send it to the MSU Ag extension office so you can get the fertilizer and lime requirements for next year. I would start liming now so it is working by the spring though personally I would not fertilize till then.

I would also plant a mix of crimson clover and Austrian Winter Peas. This will provide a good food source for the deer this fall and will be an excellent green manure in the spring to help amend the soil.

Now once spring gets here you can begin full bore food plot work.

You could also look at some native species management and apply some fertilizer and do some cutting to improve the native plants that attract deer. This will give you some additional areas of attraction on your property for this fall season.

Lastly, I would start keeping detailed records of your food plots and native species management activities. This way you have a way to measure your successes and a record of what has been done. This record will allow you to learn from your mistakes and successes. Plus it is helpfull to have should you decide to seek help from a wildlife or agricultural professional to get you through any difficulties.

Just my $.02

Hope it helps.
