Potential area for food forest

I've been cleaning up an area on our property, thinning out Eastern Redbud trees, still more to do. The soil in this area  is hummus rich (most of the lot is sandy clay), but super-high in potassium.  Wondering if this would be a suitable area to start a food forest?  

Video of some of this area is here (ignore the commentary which was for my kids) https://www.facebook.com/cori.warner/videos/10215854686423799/  

Should also mention I found three large black walnut trees on the Northeast corner of this stand of Redbuds.

Any comments, suggestions appreciated.

Hi Cori. The area looks very nice. Regarding you question, I think any area with trees is good for other trees (eg. Fungi rich soil vs bacterial), it's probably just a matter of choosing the right trees. What trees do people in the area traditionally plant? You can ask around and chances are those varieties are traditionally planted in the area because the suit the conditions.
