This study investigated the effect of different fertilization practices on SOC fraction and stock changes during maize cultivation. The experiment consisted of four different fertilizations; no fertilization (control), chemical fertilizer (NPK), NPK+residue (NPKR) and NPK+residue+compost (NPKRC). Dissolved carbon (DOC) and nitrogen (DON), hot-water extractable carbon (HWEC) and nitrogen (HWEN) and humic (HA) and fulvic acid (FA) were determine in the 0-10, 10-20 and 20-30 ㎝ soil layers. The yield of maize under NPKRC(13,202 ㎏ ㏊<SUP>-1</SUP>) was higher than Control(2,699 ㎏ ㏊<SUP>-1</SUP>), NPK(10,240 ㎏ ㏊<SUP>-1</SUP>), NPKR(11,352 ㎏ ㏊<SUP>-1</SUP>). In soil properties, pH, EC, OM, TN, Avail. P₂O5 were increased when organic matters applied in soil. The content of soil organic carbon(SOC) was higher in order: NPKRC(4.7 g ㎏<SUP>-1</SUP>) ＞ MPKR(3.4 g ㎏<SUP>-1</SUP>) ＞ NPK(2.9 g ㎏<SUP>-1</SUP>) ＞ control(2.2 g ㎏<SUP>-1</SUP>). The highest SOC stock was observed in NPKRC(21.8 ㎏ C ㏊<SUP>-1</SUP>) due to the high SOC and low bulk density. This pattern is same with HA and FA content. In conclusion, application of organic matter increase maize yield, SOC stock and concentration of labile carbon and stable carbon. Therefore, it is recommendable for suitable soil management strategy to improve soil fertility and increase crop yield in upland soil.
