| Abstract: | Chemical structure of fulvic acids extracted from composted com stalk residue(CSR FA)was studied by Fourier transform infrared (FTIR)spectroscopy, 1H and 13C nuclear magnetic resonance(1H-NMR, 13C-NMR) spectroscopy. The results show that CSR FA mainly consists of four types of carbon: carbonyl, aromatical, alkyl and carbohydrate, the carbohydrate is dominant. Its aromaticity is 15.42%, less than that of CSR HA. This indicates that the construction of CSR FA is simpler than that of CSR HA, FA can not be extracted from undecomposed com stalk residue. CSR FA may be formed by cellulose or hemicellulosemorties combined with aromatic compound from decomposed lignin. |
