In the corner of the poly tunnel, Rory built a pallet compost pit and both he and I filled it with a cube of horse manure. Rain water was added. A week later I was interested to see if the temperature inside the middle of the pile had started to climb. The probe was pushed into the middle of the pile.
The ambient temperature is 23.5C / 74f with a humidity of 58% The manure is cooking at 55.3C / 131.5f
When I finished this evening, the ambient temperature had dropped to 15C and the manure was unchanged at 55C. It will be interesting to see if it climbs any higher
