The Relationship between Microbial Characteristics and Glomalin Concentrations of Controlled Horticultural Soils in Gyeongnam Province

초록

Glomalin has been suggested as an enhancer for soil stability by promoting the aggregation. In this study, weexamined the concentrations of glomalin and microbial characteristics in 25 controlled horticultural soilssampled from Gyeongnam Province. Total glomalin had a significant positive correlation with soil organicmatter (p < 0.01), soil microbial biomass carbon (p < 0.05), and dehydrogenase activity (p < 0.05) in controlledhorticultural soils. In addition, the total glomalin had a significant positive correlation with concentrations oftotal fatty acid methyl esters, Gram-negative and Gram-positive bacteria, fungi, and arbuscular mycorrhizalfungi in controlled horticultural soils (p < 0.001). In conclusion, the concentration of total glomalin could bean indicator of microbial biomass richness for sustainable agriculture in controlled horticultural soils.
