a thought

a poor man's rock dust / mineral source could be found at the side
of the road at any road intersection ?

i was lacking sand and didn't wish to purchase a bag of it..
so i thought i'd go sweep up some from the road side at the intersection ...
hmmmm, this stuff is dusty and mostly rock (some glass) ..
i double-sifted it and i think it has potential.

1st sift large rocks, etc. out.
the second sifting resulted in about 4-8 sand grain sized pebbles and
the dusty dirt / rock smaller than those.

the 4-8 grain size should be good for fungi to break down for feeding minerals to the plants as well.
