| Abstract |
Organic residue quality has influence not only on soil organic carbon (SOC) accumulation but also on its composition. This study aimed to assess SOC composition in soil treated with biochemical contrasting organic residues for 13 years compared to 22 years treated soil using synchrotron-based FTIR microspectroscopy which is the technique that give high resolution to detect organic carbon composition in soil. Four organic residues used in this study were control (no residue addition), groundnut stover (high nitrogen (N), low lignin (L) and polyphenols (PP)), tamarind litter (intermediate contents of N, L and PP), rice straw (low N, L and PP but high cellulose (CL)) and dipterocarp leaf litter (low N, high L and PP). SOC composition of 13 and 22 years treated soil were found the same and different functional groups. The additional organic functional groups in 13 years treated soil was aromatic COO-stretching. In 22 years treated soil, the additional organic functional groups were -NH stretching of secondary amine, amide, carboxylic acid O-H stretching and aliphatic C-H stretching. The results of relationships between SOC composition and the biochemical composition of organic residues of 13 and 22 years treated soil showed the negative correlation between N content in organic residue and aromatic COOstretching in 13 years treated soil but positively correlated with -NH stretching of secondary amine, amide in 22 years treated soil. In addition, L and PP were positively correlated with carboxylic acid O-H stretching. Moreover, CL was positively correlated with aliphatic C-H stretching in 22 years treated soil. The results indicate that a shift in SOC chemical composition may be associated with organic residues biochemical composition and time that might continue affect soil fertility and productivity.
