We have, according to various recent studies, 60-100 years before there is no topsoil left globally, so we might do well to play a part in advancing the understanding of how to build soils! SoilHack is an open group created to facilitate the collaborative investigation of soil health and the development of tools and techniques for soil improvement. Those wishing to deepen our understanding of soils can do so more effectively if we share what we're learning with each other. The wiki is the homepage for SoilHack. You will be able to access everything else from here.
