The chemical and biological properties of the soil are important factors affecting crop productivity and soil health. Therefore, main purpose of this study was to investigate the chemical and biological properties of soils managed organically for over five years in the Chungbuk region, as well as the correlations among these properties. As a result of the analysis, the soil in the northern region generally had higher pH (7.4) and soil organic matter (45.1 g kg<sup>-1</sup>) compared to other regions (p < 0.05). In addition, it was confirmed that calcium and magnesium tended to accumulate excessively as the soil organic matter increased. On the other hand, the overall enzyme activity and soil respiration tended to increase according to the soil organic matter. In particular, the accumulation of organic matter significantly promoted dehydrogenase (149.3 TPF μg g-1 24 h<sup>-1</sup>) and urease activities (210.0 NH4-N μg g-1 24 h<sup>-1</sup>), which are interpreted as the result of enhancing the microbial organic matter decomposition and nitrogen cycle process. These results suggest that while soil organic matter has a positive effect on soil microbial activity, excessive accumulation of cations can have a negative effect on crop growth and soil health, suggesting the importance of balanced organic matter management. This study provides important basic data for evaluating the soil health of organic farmland, and suggests the need for future research to elucidate the effects of these characteristics on agricultural productivity and environmental health.
