[Terrapreta] Sugar, use on soil

[Michael Bailes]

This is from post 53 of the original Terra preta thread of Hypography.

Low temperature woody charcoal (not grass or high cellulose) has an
interior layer of bio-oil condensates that microbes consume and is
equal to glucose in its effect on microbial growth (Christoph Steiner,
EACU 2004).
 High temp char loses this layer and does not promote soil
fertility very well.

So perhaps sugar and charcoal do similar things???
