Yes …. I would plant a blueberry farm. They love acidic soil.
Acid-Loving Fruits
Homestead-favorite acid-loving fruits include cranberries, blueberries, elderberry, huckleberries, thimbleberries, and gooseberries, all of which perform best in soil with a pH of 4.0 to 5.0.
Acid-Loving Vegetables
Sweet corn and cucumbers also like acidic soil, doing well in soil with a pH of 5.5 to 7.5…. Beans, broccoli, turnips and tomatoes, squash, and onions.
I'm sure it would work like a charm and that is a nice place to live as well - lol
I thought it was the tannin from ther pine litter:

Acid and Herbicide, two entirely different things. Theres a reason there's absolutely no blueberry or pretty much anything else in a pine forest, I have a bit of pine woods, and I've been among the Giant Sequoias, guess what, only ferns and an odd shrub.
My blueberry bushes love growing among my White pines.
Interesting, I've seen manzanita and oaks, some birch, but no fruit trees, no berries in pine forests, in North Carolina I've seen entire swaths of only pines.
Meanwhile …. Here in Canada and USA ….
All along Lake Superior, Lake Huron, Lake Michigan and Lake Ontario …. the White pine and blueberries grow side by side.
Wherever the pine needles blow ….
So all along the sunny meadows next to the Pine trees is where you will find the best blueberries….
It’s also where you will find the Black bears.
Anything else?

Not really in the forest at all, surrounded by pines. More like on the periphery. Probably because the sun.
Here on our beach on Lake Superior the best patch of wild blue berries are growing directly under a stand of Pine Trees.
Its probably the combination of lots of moisture, good mulch, plenty of sun.
A stand isn't a forest though, like the forest you posted.
