I just started composting a couple months ago. My first try was not to schedule, it was supposed to be ready in 12 weeks, but it appears to be breaking down anyway. I done the layer method as described in #4. My mistake, I think, was watering after each layer. I have a square bin made from 3x3 tin sheets, oh yeah, the back is a recycled car hood from my teenagers fender bender! LOL
Anyway, I became impatient and opened up the bin and turned it last Sat. What I found was areas that appeared to be composting nicely, but some areas were matted leaves that didn't appear to be composting. I believe this was from overwatering when I first put them in.
So I mixed everything up real good and covered it so the sun could heat it up. I think it's hard to mess compost up, but you do have to be careful using manure because of the bacteria. They recommend a 140* to 160* internal temperature on the pile and to achieve this, you need a minimum 3 cubit square feet, from what I have read. I also read on a Washington U. release on composting that the layer method was no longer recommended, that the preferred method now is to mix everything up and turn it every so often. Which kind of contradicts letting it sit and heat up???
I have decided that when mine looks like uniform soil and I can't recognize the chicken poop from the oak leaves, then it's good to go!
