Label:chem

Topic
Geosmin is a well-known volatile organic compound (VOC) with an earthy smell, associated with wet soil.
Answer
Geosmin is an earthy-smelling compound found on wet soil after rain. It has been shown to attract soil-dwelling invertebrates, which in turn help geosmin-producing Streptomyces species disperse their spores.
