Abstract: Utilization of clippings as a recycling resource on a golf course were studied using a composting experiment with turf-grass clippings mixed with chicken dung organic fertilizers at ratios of 100%∶0%, 90%∶10%, 80%∶20%, and 70%∶30%. Microbial inocula were added to improve clippings for reuse on golf courses. The composting maturity was determined by testing temperature, pH, and germination index during composting and matured composts were analyzed for nutrient content. The four matured composts mixed with fine sand at a ratio of 1∶1 were evaluated as turf growing media using Zoysia japonica cv. Lanyin No.Ⅲ and measuring turf-grass density, coverage, chlorophyll content, aboveground biomass, and underground biomass. Clippings mixed with 20% organic fertilizer were suitable for composting, but needed 21 days to be well matured with an appropriate pH, good fertility, and safety. The compost mixed with sand significantly increased the turf quality, so that the golf course clippings could be reused as a resource for turf growing media.
