This study was carried out to evaluate effect of consecutive application of organic matter on soil chemical properties and dehydrogenase, acid phosphatase activity in non-volcanic ash soil during three cropping season. Organic matter mixture and organic fertilizer (MOF, 2,000 kg 10a<sup>-1</sup>), food waste compost (FWC, 2,000 kg 10a<sup>-1</sup>), and pig manure compost (PMC, 2,000, 4,000, and 6,000 kg 10a<sup>-1</sup>) were applied for each cropping season. Soil pH values were increased after three cropping season in all treatment. In the soils of the increased application of PMC, soil pH, total-nitrogen, available phosphate, exchangeable cations (K, Ca, and Mg), and heavy metal (Zn and Cu) contents were increased. In addition, Soil dehydrogenase activity was significantly increased in proportions to PMC application rate and cropping season during potato cultivation period. The activity was two times higher in PMC (4,000 kg 10a<sup>-1</sup>) than control after the third cropping season. Soil dehydrogenase activity was in order of PMC>FWC>NPK+PMC>MOF. Acid phosphatase activity was higher in PMC (6,000 kg 10a<sup>-1</sup>) than other treatment. Soil Zn content and dehydrogenase activity showed linearly correlation, which were MOF (R<sup>2</sup>=0.427), FWC (R<sup>2</sup>=0.427) and PMC (R<sup>2</sup>=0.411, p<0.01), respectively. This study demonstrated that soil chemical properties and enzyme activity could be affected greatly by consecutive application of different organic matter in the potato cultivation field.
