Permanent Soil Improvement Experiments w/ Biochar Continue, Catch Pit for Artichokes

This is the fourth such experiment in long term deep soil modification using a simple system of trenches or pits.  For now I'm using the term catch pit.  The basic concept is a hole where you toss in stuff that builds soil and feeds plants, backfilling with charcoal and dirt as you go.  It's cool.  Everyone should do it so we can find out how well it works.  I think default thinking these days is to let someone else prove things first, but I think that is backwards and everyone's context is different anyway.  I'm not just interested in how the finished soil performs, but how it ends up fitting into people's lives.  To me that part is just as interesting.  A society that feels an obligation not to waste soil nutrients and to build soil for the future is the one I'd like to live in, so that's what I'm doing.  I don't really know about the state of the rest of the world, but I think America would benefit from picking up a shovel more often and investing in an uncertain future.
