There seems to be little chance of building AM by the conventional, open a bottle and pour methodology. The single best way to get AM is to grow plants that have AM associations. Annuals are a great way under trees. Plant carrots and they should drive down to a depth at which soil density is...
Glomalin is the gylcoprotein discovered by Sara Wright that seems to be the prime mover in the gluing of soils particles into aggregates that then are described as structure.
Pretty basic stuff from two decades ago.
Build Arbuscular Mycorrhizal fungi and reap the benefits. While compost is...
EAB does not eat wood, it eats cambium, therefore it does not cause strength loss.
Decay causes strength loss.
Assess the tree as you normally would. Any tree with decay can break or collapse so do your normal checks.
