My soil is very alkali. Is this a good idea?

humic acid is a somewhat weak acid which
is probably just leached from humus aka
rotten organic materials. probably no
better than what you would get from buying
bags of wood chips and letting them rot.

as you are trying to do things inexpensively
i always say go for whatever free organic
materials you can scrounge and keep growing
and harvesting weeds as well.

the mention of elemental sulfur as a pH
adjuster is ok, but what do you have to
hold that element in place? if you have
no topsoil, clay or loam it may mostly wash
or leach away.
