Thanks very much, I like the way you make soil!
"First, a dump truck of pine bark!"
Do you find that the beds subside much after 2-3 years as the bark decays?
Did I read it right that you didn't add any of your clay soil at all? I think a LITTLE clay is great for buffering mineral nutrients and making clods and peds more solid. If you want any clay in the mix, I would break the clay up first by mixing it finely with sand or sandy soil. Then add and mix well some fine bark and compost to keep it from clumping again. Then I'ld add about 5% or 10% of that mix to the great organic soil you described.
