Healthy soil and sustainable growing

[Emery Mitchamore <emitch@att.net>]

The other day I attended a presentation (Butterflies as Botanists, of all 
things), given by a scientist (Pathologist), in which there was a good deal 
of information about the relative amounts of Nitrogen and Carbon in various 
forms in plants and flesh.  Most of this was new to me and I want to 
understand more.  Can someone suggest a good source of layman-level 
information about the subject substances and our need/ability to utilize?
