The edaphotron visualizes an under-appreciated process, the formation of soils, with a wall-mount enclosure, natural materials, live organisms and electronic components. Bonsai soil gravel simulates weathered rock parent material, slowly blending with organic matter created as invertebrate animals, fungi and bacteria decompose forest leaf litter. A microcontroller and other parts in a t-slot array monitor temperature, humidity and volatile gas composition inside of the edaphotron, while also driving air pump air circulation.
