Going Bananas

This topic refuses to go away.
I forgot all about this one.
Ive also heard of wood chips as mulch limits
the absorbtion of nitrogen.
What some people do is mix in
manure or sulfate of ammonia with the wood chips
to supplement that limitation of N2 uptake.
Are there other sources of carbon other than biocharcoal?

Wouldnt regular wood chips/nuggets provide the same carbon source?
After all, the basic building block of organic matter comprises of CHON.
What we do is just recycle into differents
forms of carbon/hydrogen/oxygen/nitrogen.
