Each pallet box is used to grow crops for about 8 to 12 months before I open the box to harvest its contents. This translates into two back-to-back short season crops (beans, potatoes, etc) or one long season crop (turmeric, taro, yacon, etc).
Typically a pallet box is half full when I harvest the compost/soil. The material has decomposed that much over time.
Above is the most recent box I've opened, and it is half full, as anticipated.
While I could simply fork the material into a wheelbarrow and cart it to the nearest garden bed in need, I prefer to sift out the coarser chunks. This makes my life easier when running the rototiller in the garden. Usually I use a wheelbarrow to catch the sifted compost/soil, but in the above photo I'm using a 5 gallon bucket. Don't ask me for a logical reason. It's seemed ok at the time. But really, it would have been far better to use either the wheelbarrow or the cart behind the ATV. Geez, I sifted the entire pallet boxful before I thought to use the ATV wagon. Poor decision on my part. Hopefully I've learned my lesson enough to remember for next time.
Anyway......here's a close up view of the coarse stuff that the sifter takes out.
I usually get one trashcanful, or a bit more, of coarse stuff.
