It happened. The thermometer in the compost pile reads 160 degrees. The grass clippings and coffee grounds did it.
This should not matter to me. Organic matter does not need to heat up in a giant pile in order to become compost. I know this. I have had a compost pile since I was 12 years old. Compost happens without too much effort from us other than piling up the stuff, getting it wet, and waiting. Unfortunately, a couple of years ago I took a master composter class. They taught us about bacteria, yeast , and fungi. We were schooled in the importance of carbon to nitrogen ratios. We learned how important oxygen is to a composting system. Lectures were given to us on the need to reduce waste in our landfills. We made a compost pile, watched it heat up, turned once a week for three weeks, and it made compost. We were then sent out into the big wide world to teach others about compost.
What I came away with was a competitive need to have my compost pile get hot. It became and obsession. I tried and failed. I had a faulty thermometer. The compost pile got sort of hot at 140 degrees. Today, I have finally succeeded. This is my hottest compost ever.
