    Glomalin-related soil protein has been suggested as an enhancer for soil stability by promoting the aggregation. In this study, we examined the concentrations of glomalin and characteristics of microbial community in 20 paddy soils sampled from Gyeongnam Province. Total soil glomalin as glomalin-related soil protein (GRSP) had a significant positive correlation with soil organic matter (p<0.01) and soil dehydrogenase activity (p<0.01). The concentration of GRSP significantly correlated to soil microbial biomass carbon (p<0.001) and the total bacterial community (p<0.01) in paddy soils. In addition, the GRSP had a significant positive correlation with gram-negative bacteria community (p<0.05) and ratio of cy19:0 to 18:1ω7c (p<0.05) in paddy soils. In conclusion, the concentration of GRSP could be an indicator of soil health that simplify the inspection steps for sustainable agriculture in paddy soils.
