I was planning to fork in 2 inches of compost and then mulch with 2 inches more every time I weeded this year, which is about every week or two. The soil just eats up everything I throw into it. We have small wood chips and straw, will probably add some of those on top.
I see P/K, but I don't see N in the soil test, maybe I'm missing something. I read that N isn't an important testing parameter, unless it's right before you sow.
Perhaps because this test was taken right after the summer growing season when everything was pumped out. Or I took bad samples, which is possible.
The garden was surprisingly full for such a bad test. Lots of heavy feeders (tomatoes, celery, peppers, etc). They seemed healthy but slow, but I attributed that more to a lack of water and not nutrients. It was a 4 month drought and I have water supply issues.

Many conversations and a lot of work from a lot of people and PRESTO! We are having a workshop in October of 2012 complete with Ernie's shippable core. It was more "sculpted" than "cast", but, hey, it was a prototype. We thought we could get the materials for under $100. Then came the shocker: more like $500. Urk! Work, work, work .... lots of other people involved .... work, work, work ....
I came up with a simple idea of the wood box style shippable core shortly before the October 2013 workshop and offered "build your own" at the event. In the five days before the event, a LOT of innovation happened and three different shippable cores were created. When people arrived, we showed what we had come up with and people were asked which they wanted to build and take home. Nobody wanted mine (wood box style) nor ernies (an improved version of the 2012 stuff - still very expensive). The big winner was Erica's cast core with a manifold:
In second place was Erica's cast core that did not include a manifold. Erica is clearly the big winner.
Unfortunately, that core went to the tipi outside and was subjected to freezing and thawing before it could be fully heated properly. So it developed cracks. But Erica's work led to lots of inspiration and then perspiration. Erica came back and worked with my brother Tim to come up with better molds, better mixes of castable stuff and something like a poor man's kiln to properly cook the core.
We have one core here now that has been fired about 40 times and seems to be holding up. Costs have been gut wrenchingly high ...
(I would like to take this moment to thank the people that have supported my kickstarters)
.... but we are working hard on being able to get a design completed that will be able to shipped to somebody's door (in the US) for a total of $500 or less.
Plus, several people who attended the workshops went home empty handed. Those people will get the prototypes that seem to keep working.
....
I want this thread to be the central place for all things involving a shippable core.
For all of the information being developed here, I plan on sharing it. We (me, Ernie and Erica) are still open to the idea of supporting somebody who takes these designs into production for a business. Ernie and Erica are powerfully focused on R&D and I have a powerful need to see this product exist (and no interest in being in this particular business).
I do know of one guy that I have spent a few hours on the phone with .... and he has been here .... and he has some amazing ideas in shippable cores - but I am sworn to secrecy. I really hope to someday see his product.
I think there is a lot to be said for this design, once it gets some manifold stuff added to it:
Matt Walker has created something that might have beaten us all to the punch:
I wonder how much it costs. How big it is. How do you connect it to the mass? It certainly has a wood feed, riser and manifold.
Dragon heaters has had something out for a while now, but every time I look it seems to have two or three things that fall short of what I am looking for. I have great hopes that their products will evolve into something that I wish to support.
I was unsure how to build the heat riser and then looked up Cement tubes, and found that basalite has a lovely 8" diam X 12 " flue liner made of clay. I bought that for $17.
