The amino acid concentration and composition of plants and microbes as biological factors related to the pedogenesis of Melanudands and Fulvudands were analyzed and compared to that of Andisols. Humic acid extracted from charred residue of Japanese pampas grass (Miscanthus sinensis) was also analyzed. The results were as follows : 1) The amino acid concentration of plants ranged from 380 to 730 mmol kg^<-1>, that of fungi from 1100 to 13000 mmo1 kg^<-1> and that of bacteria from 7400 to 19000 mmo1 kg^<-1>. The amino acid concentration of humic acid extracted from charred plant was extremely lower than that of humic acid extracted from Andisols. 2) Although the dominant amino acids in plants and microbes were aspartic and glutamic acids, followed by glycine and alanine, the proportion of amino acids in each organism differed. Humic acid of charred plants was rich in proline. 3) Multivariate analyses indicated that amino acid composition of plants, microbes and humic acid of charred plant was different from that of Andisols.
