PDC LESSON 7.4 COMPOST - CARBON RICH SOURCES
Carbon rich sources
Are Straw,
leaves, woody matter, corn stalks etc. are brown Nitrogen rich sources:
Fresh
grass clippings, kitchen waste, animal manure etc are green
30 parts
of carbon to 1 part nitrogen
All plants contain both elements, but one may be dominant.
Eg dead
leaves 40:1
Fresh
grass clippings 20:1
These two mixed together will create 30:1 ratio, which is ideal. Air and water- keeps the heap aerobic. Turn the heap at intervals.
