In response to the present developmental stage of Andisol classification, it is imperative to work out a simple, but very effective method to differentiate Melanic Andisols from Fulvic Andisols. Although both have a high content of humus, that of the former is characterized by A-type humic acid whereas that of the latter by B or P-type humic acid. To achieve a distinction between A-type humic acid and non-A types, an index called "melanic index" has been proposed and a simple procedure to determine the index has been worked out. Testing of the index with 132 volcanic ash samples from various countries of origin has clearly revealed its usefulness.
