경남지역 논 토양 토성에 따른 미생물 군집 변화

The present study evaluated the soil microbial communities by fatty acid methyl ester (FAME) method in paddy soils at 11 sites for silt loam, 4 sites for sandy loam, and 5 sites for loam in Gyeongnam Province. The FAME content of fungi in loam (76 nmol g -1 ) was higher than that of in sandy loam (45 nmol g -1 ). Sandy loam had significantly lower ratio of cy19:0 to 18:1ω7c compared with that of silt loam (p〈0.05), indicating that microbial stress decreased. In addition, actinomycetes community of loam was higher than that of sandy loam.
