Organic Gardening:
Carbon:Nitrogen ratio of common compost materials
by Frann Leach
Looking for something else?
The centre of any good organic garden is its compost heap. To make good compost, it helps if you are aware of the carbon:nitrogen balance of the materials which you are putting in it. This is a list of the most common materials added to compost heaps.
Crushed egg shells, feathers, bracken, tea leaves, bonfire ash and pet hair can all be added in small doses.
The following items should not be composted: leftovers containing meat or fish, large quantities of sawdust or wood shavings, evergreen prunings, manmade fibres, vacuum bag contents unless all your carpets are wool.
