Peter's Rules of Composting - A 12-Part Series
Rule 9: It's Important Critical to Make Mistakes (However, Small Mistakes are Better than Large Ones.)
As I said in Rule 2, "To learn to compost one must compost". Developing a good compost mix and adjusting the rate of aeration (i.e. frequency, duration and volume of airflow) is largely a trial and error process. I believe that figuring out what doesn't work is considerably more important than figuring out what does work.
Composting is all about working within acceptable ranges (see Rule 7), and as long as we stay within these ranges, the process tends to sort itself out in the end. Pushing the limits on these ranges (C:N, bulk density, moisture content and airflow) to the point where the composting process doesn't work has reinforced my respect for these ranges.
The following is a quick story to emphasize this point.
I live on five acres outside of Snohomish, Washington - a small town on the "rural fringe". I have constructed several prototype compost systems and tested them with every variety of organic waste that I can get my hands on.
Back in 2008, a friend of mine and I filled one of my Micro-Bins with a mix of about 1 cubic yard of separated manure, 1 cubic yard of horse manure, and 600 pounds of salmon. If you are wondering ... that's a lot of salmon. I'm guessing that the C:N of this mix was somewhere south of 10:1 (very high nitrogen). I fully expected this batch to have a strong odor so I took precautions to cover and ventilate the top of the pile and treat the off gasses in a biofilter. Unfortunately, I didn't make the biofilter large enough and let's just say that my backyard smelled like low tide for about a week.
I've lived at the same place for 20 years and in that time we have seen a lot of wildlife, but that week - for the first time - we saw a bear. It was the talk of the neighborhood. It's also interesting to note that we haven't seen a bear since. My neighbors know me pretty well and were kind enough not to complain. However, they did ask "What do you have going on over there this time?" Which leads me to ...
The First Axiom Rule 9: "Experience is what you get when you don't get what you want."
The Second Axiom of Rule 9: "If it's worth doing, it's worth doing poorly - at first."
The Third Axiom of Rule 9: "Don't stink up the neighborhood."
