Pallets are a good building material, so I built with pallets.
And pretty soon, thanks to contributions from the neighbor's leaf-raking efforts, even the enlarged version was too small.
Then I realized I couldn't turn the compost, couldn't mix it.
And the straw & sawdust from the chickens wasn't doing anything more than just sitting there. It was dry and dusty, a month into the rainy season!
Time for another upgrade. I doubled the width (thanks to some extra-large pallets from a local spa shop). Now I have room to turn things. But what a mess.
And it's still all carbon: tree leaves, straw, sawdust (with a little chicken poo and horse poo mixed in).
As I moved the pile from one side to the other (by hand, with a pitch fork!), I layered it with fresh produce & juice pulp, used coffee grounds and shovels full of "starter": successful decomposition (thick with red wrigglers!) from the two worm bins in the back yard.
I hope I got enough nitrogen in the mix to balance the immense carbon load, but I think I got a good start. Next month, I'll fork it all over to the right side again, and add either carbon stuff or (more likely) more nitrogen to keep it even.
Let's see how this turns out come spring!
