Supporting evidence for the universal usefulness of NaOCl in removing organic matter from soils is needed. Apart from its higher efficiency in organic matter destruction, NaOCl adjusted to pH 9.5 was found to be an effective dispersing reagent for savannah soils (which make up over 60% of the land area of Nigeria) during particle size analysis. The additional discovery of the use of NaOCl was considered to be very significant over the conventional H 2 O 2 method where extra treatment with (NaPO 3 ) 6 was needed to obtain dispersion. However, in the case of fine textured forest soils it was found that for them to be in the dispersed state, additional washing with 2% aqueous Na 2 CO 3 ‐HaHCO 3 must be performed after the NaOCl pretreatment.
