Soil is filled with life. Whole communities, some of them very complex and with distinct functions, are literally right under our feet. In fact, the majority of rangeland ecosystem diversity occurs belowground and up to 90 percent of the total productivity of rangelands occurs in the soil. Think of that shovel full of soil as hiding a thriving, dynamic, and very busy community, with different organisms filling important roles to make the whole thing work.
