The present study was aimed to evaluate the soil microbial communities by fatty acid methyl ester (FAME) method in paddy soils at 20 sites in Gyeongnam Province. The soil microbial biomass carbon content of fan and valley 1,266 mg kg-¹ was higher than alluvial plain 578 mg kg-¹ (p less than 0.05). In addition, The dehydrogenase activity of fan and valley 204 ㎍ TPF g-¹ 24h-¹ was higher than alluvial plain 93 ㎍ TPF g-¹ 24h-¹ (p less than 0.05). The communities of total bacteria and Gram-negative bacteria in the fan and valley paddy soils were significantly higher than those in the alluvial plain paddy soils (p less than 0.05). Total bacteria communities should be considered as a potential responsible factor for the obvious microbial community differentiation that was observed between the fan and valley and alluvial plain in paddy soils.
