[soilhack-announce] Fw: Terra Preta workshop

Hi everyone, Nir Halfon and myself have organised a Biochar and Tera Preta workshop at Plaw Hatch. Just one day on the 24th September. I've done this workshop in Germany, and liked it. We were shown simple ways (earth funnel) to make biochar, and then set up a terra preta heap so anyone who's interested, please come Dorothea
