Nicole Masters, author of For the Love of Soil, has mentioned Betzy Ross (sp?) In Texas doing work with Mesquite trees; she studied them and made a profile of the elements that the tree was good at bringing up from the soil, put rhat stuff together with fulvic acid and other materials and the mesquite trees died. She said if you look at what the plant is trying to address, then you can shift something in the soil that apparently makes it more or less likely to grow certain things. (Regenerative agriculture podcast, episode #72. You'll have to listen or read her book to get a better understanding. That is the best I can do with a 2.5 year old running around me.)
Years ago I seem to recall reading that poison ivy was in areas low in calcium. I tried ro find that resource but cannot anymore. Another page said that it was likely to grow in places low in other things, and that it liked soil a little acidic.
Perhaps there's something else we can do to shift soil health in favor of other plants?
Anyone know if adding mycelium, or vermicompost, or benefiting soil health in general has helped the poison ivy control?
Or anyone able to speculate on whether the items planted around them are showing signs in low calcium, phosphorous, etc.?
