I would have the soil tested to see what you have and then know what is needed

Agree. Get a professional soil test done by your local county ag extension office. Costs $10-12 dollars in most places. That's the only way you'll know exactly what it needs.

In the mean time scout for a local source of bulk compost and a 25-50lb. bag of cottonseed meal or alfalfa meal to bulk up the N levels to cope with all the bark and wood chips. Just don't apply until you get the soil test back. Normally has a 1 week turn around time.

As several folks have mentioned in your other thread on the sickly tomatoes, the questions about sufficient sun exposure and planting methods are also problems for you that need to be resolved. Even with ideal soil mix if there isn't sufficient sun exposure you are going to have difficulty.
