Resumo: Electron Paramagnetic Resonance (EPR) spectroscopy was applied in whole soil samples (Gleysoil). The objective of this work was to quantify the degree of humification of the organic matter of the soil, whole soil (Gleysoils) without any chemical treatment, and to compare with its organic-mineral fractions. The signal of semiquinone free radical was detected and quantified showing close relationship with its organic-mineral fractions.
