Nodal Farming

Trees in a forest are nodes. The older the tree, the more likely it has many connections to mycorrhizal networks. If seedlings can "plug into" a pre-existing fungal network they have a more robust growth pattern.

If the "old" nodes in a forest are destroyed by, say, logging then the entire fungal network is diminished and seedlings are less likely to find a fungal partner to plug in to and therefore have a less robust growth pattern.

It's actually in a logging company's best interest to leave the old growth trees as nurse-maids, plant seedlings among them, and then harvest those young trees an a few years time. They will grow faster and have better structure than seedlings planted on a clear cut site with no fungal network to plug in to.

Wow, shit I've never considered. I need to get some of our land logged. I bet if I brought this up to a local logger he'd ask what I've been smoking. Almost want to buy my own mill at this point. I'm on 30 acres and most of our trees I could handle with my tractor and my dump trailer.

I love this note Fren

This is what I believe they are calling working forests around here. Not all do it, but more are doing this. The land I am on now did it this way. It was cleared in 1994. But scattered about we have some trees over a 100 years old. Of course not old growth but better than clear cut.

That's interesting. Do you have any pictures of the land (something that doesn't doxx your location)?

I would need to take a drone shot in order for there to be any perspective. Unfortunately, the drone I have hasn’t worked in a long time.

Understandable.

Reminds me of a trial shown in the Soil Food Web School's course. They applied compost extract (with all the functional groups of microbes including fungi) to young Christmas trees. After the first year the control and experiment trees looked the same, but they found the root system on the treated trees was twice as large as the control. The next year the treated trees grew twice as much as the control trees. After that the farmer wouldn't let them take pictures anymore because he didn't want his competition to see the results.

Trees (and all plants) pump energy into the soil, and the soil food web feeds on it to make nutrients available to plants.

Is there any evidence or research that a stand of trees connected by a mycelium network could generate heat? I was noticing some interesting patterns in the snow melt this week.

Not that I’m aware of but wherever there’s metabolism, there’s heat.
