· Some of the richest, most fertile soil on the planet is found near active volcanoes, which explains why people throughout civilization have been willing to settle near volcanoes despite the potential dangers. In the 1930s, researchers in Europe used finely ground rock dust to treat and improve the productivity of degraded forest lands.
