8. Soil Horizons

9. A Horizon: mineral horizon (shows organic matter enrichment C Horizon: least weathered horizon O Horizon: leaf litter and organic material found B Horizon: where most minerals and nutrients are found (also called the subsoil) E Horizon: only in acidic soils( known as the zone of leaching) R Horizon: Bedrock
