Active Compost Cooking - Over 100 Degrees - September 2021
A week ago, I posted some photos and talked about the new (to me) process of laying in some 'alfalfa cube soup' in my active compost bin as I turned it over and mixed the browns and greens. That layering of the material that I've collected since last Fall in the one, active bin, came after I had turned over the top of the active bin and removed all the (mostly) black gold from the bottom a week prior. We're still in the heat of Summer - with air temperatures in the 80's and 90's around here, so it is prime compost decomposition time and 'active' time in our bin.
I have measured the temperature of my bins before - earlier this Summer, I was seeing temperatures of the pile above the air temperature, but only in the 'steady' category. Somewhere between 80 degrees and 90 degrees. I posted a photo of my long-stem compost thermometer here back in July showing right around 90 degrees.
Where are we after the alfalfa soup and turning the pile and re-stacking it in the active bin? I stuck my thermometer back into the pile about 24 hours after filling it back up. And, we're now in the 'active' zone - above 100 degrees Fahrenheit. See below for the pile tipping over into that darker green 'active' area.
