Not living in a pine forest we always added what pine needles we could
muster. Recently ( the last 10 years that has increased a lot ). I
sort of have belief that a mix of life is better than a narrow use of
biological compost ingredients. So this would lead be assume a land
rich in chicken or cow manures still would benefit from other once
living things like Green sand, bone meal or granite dust for instance.

Anyway seems fungi may be a good thing to encourage in your garden but
not in your toes or groin. )

Sort of touches on pH as mentioned in another tread I can not fine.
