The aim of this study was to investigate chemical characteristic of livestock compost in association with livestock manure types(poultry, cattle, swine, and mixed manure). The livestock compost was collected from local nonghyup branches on a si-gun level. Chemical composition (nutrients, heavy metals etc.) of the samples was analyzed and Pearson's correlation analysis was performed. Quality of most compost samples met the standard of fertilizer specifications. Poultry compost contains greater nutrients especiallyP2O (p-value＜0.01) and NH4-N (p-value＜0.05). Meanwhile swine compost has higher concentration in water content (p-value＜0.05)and heavy metals (p-value＜0.01 for Cd, Cu and Zn). Overall, poultry compost was correlated positively with nutrients while swinecompost has positive correlation with water content and heavy metals. We expect that the study results can provide base data fordetermining compost types and amount for crop production
