Soil! Dirt! Earth. Dr. Lydia Jennings, aka Native Soil Nerd, breaks down the stuff under our feet and explains everything from mining to why soil can be different colors. Also: medicine from microbes, giving back to the land after extractive processes, collecting samples in urban rivers, elders’ ecological knowledge, planting hot Cheetos, potting soil mysteries, lung fungus, the smell of rain and why gardening makes you happy. Oh and running hundreds of miles for your science. Follow Dr. Lydia Jennings on Twitter @1NativeSoilNerd or on Instagram @llcooljenningsHer website: nativesoilnerd.comDonations went to RisingHearts.org and to Lydia’s film, Will Run for SoilMore episode sources and linksOther episodes you may enjoy: Geology (ROCKS), Sponsors of OlogiesTranscripts and bleeped episodesSmologies (short, classroom-safe) episodesBecome a patron of Ologies for as little as a buck a monthOlogiesMerch.com has hats, shirts, masks, totes!Follow @Ologies on Twitter and InstagramFollow @AlieWard on Twitter and InstagramSound editing by Mercedes Maitland &  Jarrett Sleeper of MindJam MediaTranscripts by Emily White of The WordaryWebsite by Kelly R.
