Large scale composting

Large scale composting

A few years back we made "accidental compost". Ingredients were a dump trailer full of wood chips and fermented wine grape pumice. Forget about said pile. The dogs running over it constantly, chasing balls, essentially kept it turned. It turned out marvelous! Light and fluffy...perfect for my heavy clay soil. This year I am recreating that compost. I have Photobucket pile of wood chips. It's roughly 25'x12'x5'. Hehe I stalk the tree trimmer guys. During harvest we will add an equal amount of pumice to the pile. Down to my question. What else would you add? I already have a compost bin. This thing is going to be massive and separate from that. I am specifically trying to amend adobe clay soil. Any input from you wonderful folks would be awesome!
