초록

본 연구는 한국잔디와 켄터키 블루그래스로 조성된 국내 대부분의 골프장들의 페어웨이를 가축분뇨액비를 활용하여 최소한의 화학비료를 투입하여 관리가 가능한지를 살펴보고, 토성별 효능을 검토하여 가축분뇨액비의 성분분석, 부족성분보충, 잔디초종별 적정 처리횟수 및 시기 등 실제적인 처리방법을 구명함으로써 향후 개발되어질 대량살포기술에 의한 가축분뇨액비의 활용도를 높이고자 수행되었다.

This study was conducted to determine the effect of slurry composted and biofiltered (SCB) solution as a substitute or supplement for chemical fertilizer (CF) on zoysiagrass turf.

This study was conducted to determine the effect of slurry composted and biofiltered (SCB) solution as a substitute or supplement for chemical fertilizer (CF) on zoysiagrass turf. SCB solution supplemented with P alone or mixture with CF (30:70, 50:50, or 70:30) based on their N contents were applied on pots to find out the optimum rate of SCB solution. SCB solution mixed with CF, especially S3C7 (SCB 30% + Chemical fertilizer 70%, 3.5 g N/㎡ + 1.5 g N/㎡) treatment, improved turf color and density. In addition, SCB2 + P (200% SCB, 10 g N/㎡ + 3 g P/㎡) treatment showed turf quality similar to CF1 (100% chemical fertilizer, 5 g N/㎡) treatment. However, the clipping yield was less at all SCB solution treatments than CF1 treatment. To determine the leaching of nutrients from a sandy soil treated with SCB solution, the drainage water from hole under the bottom of each pot treated with SCB solution or CF was collected. As the amount of SCB solution treated increased, leachate EC tended to be increased. However, N and cations (K, Ca, Mg) leaching of all SCB solution treatments were less than those of CF1-L (100% liquid chemical fertilizer, 5 g N/㎡) treatment. These results demonstrated that SCB solution could be used as a supplement or substitute for CF, alone or mixed with CF.
The second experiment was conducted to determine the effects of application amount, timing, and frequency of SCB liquid fertilizer on Zoysia japonica ‘Millock’. The SCB liquid fertilizer was applied at low, medium, and high amount (N at 15, 25, and 40 g·m-2 per year in 2010, and 10, 20, 40 g·m-2 per year in 2011, respectively) and treated during growing season or dormancy period. During growing season, SCB liquid fertilizers were applied twice and four times. SCB plots applied four times with N at 40 g·m-2 per year during growing season (SH4) improved the highest turf quality in both years. Plots treated during dormancy period showed high turf quality. SH4 exhibited turf color retention in the fall, and enhanced clipping yield during growing and fall seasons. SCB plots applied four times during growing season (SL4, SM4, and SH4) increased shoot density compared to the other SCB treatments applied with the same amount.
