G.  aComparison of total nitrogen methods applied for histosols and soil horizons with high organic matter content.h[electronic resource]  c2006  aThis 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.  aTropical soils  aHistic horizons  aSoil chemical1 aESPINDULA JÚNIOR, A.1 aVALLADARES, G.
