Svartjord

Jordprofil fra steppereservatet utenfor Kursk i Russland

Svartjord (fra russisk чернозём, tsjernoziom, «svartjord») er et nesten helt svart jordsmonn med opptil én meter dyp humus. Svartjord skapes i grovkornet, veldrenert og kalkrik jord, og forekommer først og fremst i steppelandskap.[1] Svartjord er blant verdens mest fruktbare jordsmonn, og en stor del av verdens hvetedyrking foregår i slik jord. Store områder med svartjord og lignende jordtyper finnes nord og øst for Svartehavet, i Mellom- og Sørøst-Europa, på prærien i Nord-Amerika og på pampasen i Sør-Amerika.[2]
