This study evaluated the soil microbial communities by fatty acid methyl ester (FAME) method in soils (6 sites for immatured paddy, 9 sites for normal paddy, and 5 sites for sandy paddy) in Gyeongnam Province. The soil microbial biomass carbon content in normal and sandy paddy were 1,235 and 441 mg kg-¹, respectively, showing the soil microbial biomass carbon content in normal paddy was higher than that in sandy paddy. The soil organic matter contents 33 g kg-¹ of immatured and normal paddy were higher than sandy paddy 18 g kg-¹ (p less than 0.05). The communities of total bacteria and Gram-negative bacteria in normal paddy were significantly higher than those in sandy paddy (p less than 0.05). Total bacteria communities should be considered as a potential responsible factor for the obvious microbial community differentiation.
