Coffee has almost twice as much nitrogen as chicken manure, yet it can be spread without risk of burning. I think the woody nature causes nutrients to release slowly. Are these manures also not considered good fertilizers?
The coffee acts more slowly. When I scoop up a hand full of my coffee mulch, there are always sow bugs, worms and other critters in it. It always disappears, so I asume that they eat it. These creatures poop and they eventually die. When this happens, nutrients become available to plants.

I assumed that my piles would finish up if I left them to sit for a few months. The part that confuses me is that most sources tell you that the end product of an 18-day compost pile should not resemble any of what went in to begin with. This leads me to believe I am still not getting the correct proportion.
If adding more green material to my cooled pile causes it to heat again, does that not mean that there was enough carbon to support a greater nitrogen load in the first place?

I remember hearing (perhaps incorrectly) that the presence of this bacteria in the compost was an indicator that the temperature is too high in the pile. Is that incorrect? Since I don't have a compost thermometer, I have no idea what the exact temperatures were that my piles reached. I did the arm test after a week or so on some of them and immediately had to pull my arm out before reaching the center of the pile. The piles got roaring hot but they didn't break down all of the straw. I'm not satisfied with it as a compost product, but it is probably superior to a pure straw-mulch. I'll find a source of manure to boost my nitrogen for my future piles.
