1.1.1 Natural sources of TMEs

Soils naturally contain TMEs whose concentration, or natural pedogeochemical background (NPGR), results from the geology of the parent material from which the soil was formed (the parent rock) and from pedogeochemical processes (weathering, leaching, migration, etc.) that can lead to redistribution (depletion or accumulation) of TMEs in soil horizons.
