Descripción:	This study was carried out to correlate total nitrogen analyzed by two different methods: Kjeldahl (wet oxidation) and Perkin-Elmer 2.400 Series II?CHN Mode (dry oxidation or combustion) in Histosols and soil surface horizons with high organic matter content, sampled in different regions of Brazil. A positive correlation (r = 0.95**) was verified between the methods, showing that Kjeldahl, because of its simplicity, can be used to routinely determine total nitrogen content in the evaluated soils.
