If a figure in a log entry does not add up, or a batch behaved differently from the one described here, that is the most useful thing you can send. Include your material list, weights if you have them, and the temperature readings; a correction that comes with data gets incorporated into the entry rather than archived.

We cannot diagnose a specific pile from a photograph, advise on local regulations, or recommend products. For regulatory questions about composting food waste or using manure, your municipal waste authority is the right place to ask.

Usually within five working days. Mail about a specific batch entry is answered first because it usually improves the site.
