compost in tumbler not getting warm enough to break down
How do you measure the ratio of brown to green ingredients for breakdown. Wh. at is the proper ratio? I have tried many combinations and nothing has worked. Compost is moist but not soggy. I turn it every day or two. I have added some dirt and some manure.
The proper ratio of browns (fallen leaves, dried grass, newsprint, etc.) to greens (kitchen scraps, grass clippings, etc.) is 3-1, and the moisture of the compost pile should be soggy like a squeezed sponge.
If your compost is not warming up enough, you can add more green materials or a nitrogen fertilizer. You should not add dirt to compost.
Here is some great information about composting from the City of Minneapolis (so, any regulations mentioned may not apply to you):http://www.ci.minneapolis.mn.us/solid-waste/yardwaste/solid-waste_yardwaste-composting
