Following the launch of SoilHack at the first UK Farm Hack event in 2015, the first SoilHack gathering will be held on the 27th-28th May in Somerset, England. Details here.
Farm Hack is a worldwide community of farmers and growers who build and modify their own tools, sharing their hacks online and at meet ups - improving their practices through open-source collaboration. SoilHack was set as a subdivision of Farm Hack to provide a space for people to share their understanding of soils and help each other get a clearer understanding of how to improve their health. We have a wiki page on farmhack.org, to which anyone can contribute. So far, we've been collating good resources, running a soil events email list, a Twitter account, and giving presentations at events (including the Scottish FH last year).
