This study was conducted to evaluate the effect of application of SCB liquid fertilizer produced after slurry composting and biofiltration (SCB) on turfgrass growth in golf course during 6 month period from May to October in 2008. The change of soil properties by applying CF and SCB was unaffected respective treatments. As compared with NF, turf color index of CF, S-1 and S-2 increased by 1.8%, 2.5%, and 3.4%, respectively and chlorophyll content by 13%, 19%, and 25%, respectively. Dry weight of S-1 and S-2 was increased by 15% and 26% than that of CF. As compared with CF, N uptake rate in S-1 and S-2 was increased by 21% and 37%, P uptake rate 57% and 28%, and K uptake rate 16% and 27%, respectively. S-2 showed the best effect for turf color index, chlorophyll content, dry weigh and nutrient uptake rate in creeping bentgrass. These results suggested that an mixed application of SCB and compound fertilizer was improved turf quality and growth of creeping bentgrass by increasing nutrient uptake rate of turfgrass.

2012년 가축분뇨 해양투기가 전면 금지됨에 따라 가축분뇨의 자원화의 필요성이 대두되고 있다. 하지만 현재 가축분뇨 발생량의 일부는 퇴비화로 농경지로 환원되고 있으며, 지역에 따라 일부 지역에서는 농경지면적 대비 가축분뇨 필요량을 초과하는 것으로 나타나, 산림지 및 조림지역으로의 가축분뇨 환원이 새로운 대안중 하나로 대두되고 있다. 특히, SCB (Slurry Composting and Biofiltration) 액비는 성분이 비교적 균질하고 저농도이며 냄새가 없어 산림유역에 시비가 가능할 것으로 판단된다. 하지만, 액비 시비량에 따라 수분 및 영양성분 수지 불균형 등을 초래하여 토양에 축적될 우려가 있고, 지하수로 침출될 가능성이 있어 이에 대한 모니터링이 필요할 것으로 판단된다. 따라서 본 연구에서는 산림유역 중 백합나무 조림지인 바이오순환림과 포플러 조림지인 유휴지에 SCB액비를 시용하였을 때 지하수에 미치는 영향을 살펴보기 위하여 매주 지하수 수질 모니터링을 실시하였다. 특히, 청색증 등을 유발시켜 지하수 오염의 지표인 질산성질소를 중심으로 지하수 수질 분석을 하였으며 질산성질소의 오염원을 판단하기 위하여 질소 동위원소비를 분석하였다. 시험림의 물리적 특성이 다른 두 산림유역에서의 SCB액비 시용에 따른 지하수 모니터링 결과는 향후 지속적인 모니터링이 이루어진다면 산림지에서 SCB액비 시용에 따른 수질영향 평가 및 모델링 기초 자료로 활용될 수 있을 것으로 판단된다.

This study was conducted to evaluate the effect of developed composted liquid manure(DSCB), which was produced by adding N, P, and K to composted liquid manure(SCB), on the growth of zoysiagrass. Two different N sources used in DSCB were ammonium sulfate(DSCB-A) and urea(DSCB-U), respectively. Fertilizer treatments were designed as follows; non-fertilizer (NF), control (CF; chemical fertilizer), DSCB-Al($200mlm^{-2}$ DSCB-A), DSCB-A2($250mlm^{-2}$ DSCB-A), DSCB-U ($250mlm^{-2}$ DSCB-U) and CF+SCB(CF+$250mlm^{-2}$ SCB). In zoysiagrass, turf color index, chlorophyll index, dry weight and nutrient content were measured. Turf color index and chlorophyll index in DSCB and SCB treatment were increased by 1~3% and 14~28% than those of NF, respectively, and in DSCB-A1, DSCB-A2 and CF+SCB increased by 7~12% than those of CF. As applied with DSCB and SCB, the dry weight of DSCB-A1 and DSCB-A2 was increased by 25% and 19% in than CF, respectively and their nitrogen uptake by 19% and 6%. Evaluated with turf quality and growth, DSCB-A1 was the best and the most efficient in all treatments. These results indicated that application of DSCB-A1 promoted turf quality and growth of zoysiagrass by stimulating a nitrogen uptake, so that it was expected to replace to chemical fertilizers.

This study was conducted to evaluate the effect of developed SCB (DSCB) liquid fertilizer produced by adding N, P and K at SCB liquid fertilizer on the growth of kentucky bluegrass. Two different N sources used in DSCB were ammonium sulfate (DSCB-A) and urea (DSCB-U), respectively. Fertilizer treatments were designed as follows; non-fertilizer (NF), control (CF; chemical fertilizer), DSCB-A1 ($200\;ml{\cdot}m^{-2}$DSCB-A), OSCB-A2 ($250\;ml{\cdot}m^{-2}$DSCB-A), OSCB-U ($250\;ml{\cdot}m^{-2}$DSCB-U) and CF+SCB (CF+$250\;ml{\cdot}m^{-2}$SCB). Every treatment was arranged in a randomized complete block design with three replications. In kentucky bluegrass, turf color index, chlorophyll index, dry weight and nutrient contents were measured. Results were as follows; It was hardly affected by DSCB and SCB application in investigation of chemical properties of soil. Turf color index and chlorophyll index in DSCB and SCB treatments were increased by 1~2% and 19~24% than NF, respectively and similar to CF. As applied with DSCB and SCB, dry weight of DSCB-U and CF+SCB was increased by 36% and 10% than CF, respectively, but similar to that of OSCB-A1 and DSCB-A2. Evaluated with turf quality and growth, DSCB-U was the best in all treatment and OSCB-A1 the most efficient. These results indicated that applications of OSCB and SCB promoted turf quality and growth of kentucky bluegrass or similar to CF, so that they were expected to replace chemical fertilizers.

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.

Long-term continuous application of livestock by-products to agricultural land may adversely affect the soil characteristics and the crop yield. Five year term study from 2007 was carried out to assess the effects of repeated application of low-concentration swine slurry on soil chemical properties including phosphate and heavy metal contents and yield of tomato (Lycopersicon esculentum) and cucumber (Cucumis sativus L.) in a greenhouse. Treatments were conventional chemical fertilizers and three application rates of low-concentration swine slurry (Slurry composting and biofiltration, SCB): 50%, 100%, and 200% of recommended nitrogen fertilization. For swine slurry treatment of 50% nitrogen, deficient nitrogen was supplemented with urea fertilizer. The soil phosphorus and heavy metal contents after five year continuous application of swine slurry were not significantly higher than those of chemical fertilizer use. Repeated application of the swine slurry alone for five years resulted in relatively high soil exchangeable potassium and sodium compared with chemical fertilizer treatment. Contents of heavy metals in leaves of tomato and cucumber did not show significant difference among treatments. Yields of the crops for the swine slurry were not significantly different from that of chemical fertilizer. The results imply that continuous application of the swine slurry may not influence levels of soil phosphate and trace elements in greenhouse soils but could accumulate potassium and sodium in the soil.
