Abstract

Research was conducted to evaluate Fe transformations in a hydrosequence of Oxisols from the Central Plateau of Brazil. The best-drained member of the hydrosequence of soils selected for the study classifies as an Anionic Acrustox (Dark-Red Latosol). Differences in color and iron oxide mineralogy of soils in this hydrosequence are the result of the preferential reduction of hematite over Al-substituted goethite in the presence of a seasonally high water table. -from Authors
