Abstract

Total soil microbial activities have great impact to soil management for organic farming. This study was evaluated in the soil microbial community by fatty acid methyl ester (FAME) in a controlled horticultural field for strawberry organic farm. Experimental plots were prepared with a high level of soil electrical conductivity (EC) and a optimum level of soil EC. Soil microbial biomasses and communities of total bacteria, Gram-negative bacteria, Gram-positive bacteria, actinomycetes, fungi, and arbuscular mycorrhizal fungi in the high level of soil EC were significantly larger than those in the optimum level of soil EC. Lower ratios of cy17:0 to 16:$1{\omega}7c$ and cy19:0 to 18:$1{\omega}7c$ were found in the optimum level of soil EC than those in the high level of soil EC, indicating that microbial stress decreased.

시설딸기 재배지에서 염류농도가 생육초기 토양 미생물 생태계의 변화에 미치는 영향을 FAME 분석으로 검토하였다. 토양 총 세균 함량, 그람음성 세균 함량, 그람양성 세균 함량, 방선균 함량, 곰팡이 함량, 내생균근균 함량은 염류농도가 높은 토양이 적정한 토양 보다 유의적으로 높았다 (p<0.01). 토양 환경 스트레스 지표로 사용되는 cy17:0과 16:$1{\omega}7c$ 그리고 cy19:0과 18:$1{\omega}7c$ 비율은 상대적으로 염류농도가 적정한 토양에서 낮은 경향을 보여 토양 환경 스트레스가 적은 것으로 판단 되었으나 유의적인 차이는 없었다. 총 세균, 그람음성 세균, 그람양성 세균, 방선균, 곰팡이 및 내생균근균 군집은 염류농도가 높은 시험구가 염류농도가 적정한 시험구에 비해 유의적으로 높은 경향이었다.
