The objective of this study was to identify the relation between the redness index (IAV) of soil and the amount of carbon content present in the aerial part of Cerrado vegetation. The study was conducted in seven cities </span><span style="font-family: Times New Roman,Times New Roman; font-size: small;"><span style="font-family: Times New Roman,Times New Roman; font-size: small;">in western Bahia state, in native areas of Cerrado.
