Summary:A developed slurry composting and biofiltration (DSCB) liquid fertilizer could be used for eco-friendly turfgrass management in golf course. This study was conducted to evaluate the growth effect of application intervals of DSCB in Kentucky bluegrass based on turf color index, chlorophyll index, clipping yield and uptake and availability of nutrient. Treatments were designed as follows; non-fertilizer (NF), control (CF) and DSCB treatments which were applied a every 15 days (DSCB), every 30 days (2DSCB) and 60 days (4DSCB-1: April, June, August; 4DSCB-2: May, July, September). Turf color indexes of DSCB and 2DSCB were higher than CF, but these chlorophyll indexes similar to CF. The clipping yield and uptake and availability rate of nitrogen and potassium in turfgrass were increased in 2DSCB. These results suggested that application of DSCB improved turf quality and growth by prompting an uptake and availability of nutrients in Kentucky bluegrass and its application interval was 1time per month. 개량SCB저농도액비(DSCB)를 친환경적인 잔디관리에 이용하기 위하여 시비간격에 따른 켄터키블루그래스의 엽색지수, 엽록소지수, 잔디생육, 양분흡수 및 이용율을 바탕으로 DSCB의 적절한 시비방법을 평가하였다. 시험을 위한 처리구는 무처리(NF), 대조구(CF), 15일 간격으로 시비한 DSCB 처리구 (DSCB), 30일 간격으로 시비한 DSCB처리구(2DSCB), 4월부터 60일 간격으로 시비한 DSCB처리구(4DSCB-1), 그리고 5월부터 60일 간격으로 시비한 DSCB처리구(4DSCB-2)으로 구분하였다. 잔디의 엽색지수는 DSCB와 2DSCB가 CF보다 높았고, 엽록소지수는 CF와 비슷하였다. 질소와 칼리의 흡수량 및 이용율과 예지물량은 2DSCB와 4DSCB에서 CF보다 증가하였다. 이러한 결과들로 종합할 때, DSCB는 월 1회 시비하는 것이 잔디의 양분흡수와 이용을 증가시켜 잔디생육과 품질을 향상시키는 것으로 알 수 있었다.
