Did you by chance sterilize the soil before planting? Damping-off
fungi are common in such soils.

It is _possible_ to grow trees without mycorrhizal fungi. Those trees
do not amount to much. They require greenhouse conditions since it is
necessary to produce air, water, soil and light for the trees.
In *nature* however, such trees do not survive long. The competition
with trees which have mycorrhizal fungi is such that competition weeds
them out quickly.
Nor does this apply only to trees. Corn requires mycorrhizal fungi
present in most soils the world over to survive. But there are some
places in the world where these mycorrhizae, typically Glomus sps., do
not exist. In these places, corn seeds sprout, grow for typically 1-2
weeks, then die.

The key to the above statement is "the landowner's objectives".
Forestry is the art and science of growing trees, not just the art of
Ignore mycorrhizal fungi and trees in nature cease to exist quickly.

Gifford Pinchot's initial experiments were done under greenhouse
conditions. At that time, mycorrhizal fungi were not even known. Most
had not been described in science. (Come to think of it, not much has
changed, since a heck of a lot of mycorrhizal fungi _still_ haven't
been described in science.) Show me an old-growth tree over 100 feet
tall in any greenhouse.
That's where the fallacy is proven or disproven.

American heritage? No. But we do need them as sources for mycorrhizal
fungi that are found only on old-growth trees.
Even as a variety of trees grow on a given acre in succession leading
up to climax forests, varieties of mycorrhizal fungi grow with
individual trees leading to older trees. Mycorrhizal fungi found with
seedling trees are seldom those found with old-growth trees. The
ability to grow old-growth trees (400+ yo) is probably dependent upon
those mycorrhizal fungi in nature. Without them, "foresters" are
probably shooting themselves in the foot.
