If there is any doubt as to toxicity of materials going into a pile, do not use them. Be sure to use only organic materials in your compost piles, excluding non-organics and organics which have been treated with non-organics (e.g., plywood will decompose, but it has been treated heavily with glue.)

Notation: Two numbers separated by a colon indicate the estimated carbon to nitrogen ratio of the material. These are only guidelines and should not be considered to be exact. Compost materials should be combined to reach an ideal carbon to nitrogen ratio of (30:1).
