This is a myth.
I do not think so I am not the only one to use it and to be enthusisat

A maple that I have was a Korea grown and was in this horrid soil had
roots thin and dense looke Afro hairs

the 2 garden centers that had these plants ( recognizable by the
pinkish gravel refused to have the following year the same plants as
had too much mortality as the soil was drying too fast
My deshojo had borers I payd nothing for such a tree and it is very
alive...it makes 3 years now that is growing in such a soil

The forces that promote root splitting occur at a molecular
level & have nothing directly to do with the shape of the soil particles.
apparently it does with shape

In
addition to water & nutrients, the soil must contain air.
and when gravel is irregularly broken allws a better circulation of air
The soil particles
that promote the most air would be as round as a ball bearing.
totally wrong , for instance expanded clay suitable for
aquaculture is pushed by roots to the center of the roots pads ( my
personal experience)
Crushed granite
chicken grit
synthetic material ?
with its sharp edges makes a good bonsai soil component,
so why not using granite in europe is asily available ,.. and can be
recicloed for others bonsais
but so
does aquarium gravel with rounded edges.
first of all I prefer granite or pozzolana or lava aquarium gravel
is rounded and is good to be added to pozzolana or chicken grit or pumice

Best regards
