| Abstract/Contents: | "Many soil amendments have been used nowadays to improve physical and chemical condition of turf soil, which might ultimately optimize turfgrass growth in golf courses. This study was carried out to investigate the effects of new organic soil amendment containing pig excreta 50% and sawdust 50% on growth of zoysiagrass (Zoysia japonica L.) and Kentucky bluegrass (Poa pratensis L.) in greenhouse. Three applicable treatments with soil mixtures of 10, 20, and 30% (v/v) animal organic soil amendment (AOSA) with sand, were tested for chemical property, physical property, visual quality and root length of zoysiagrass and Kentucky bluegrass. As results, application of 10~30% AOSA mixtures showed 0.7% in organic matter, which meets to green standard of USGA. Also, 30% AOSA mixtures was 1.1% in organic matter, which might be desirable for zoysiagrass-planted golf courses in Korea. It was turned out that addition of AOSA decreased the hydraulic conductivity in soil physical property. Because the sand possesses high hydraulic conductivity, it is recommended to combine 10~30% AOSA with sand in order to sustain soil balance. The treatment with 10~30% AOSA noticeably increased visual quality of both zoysiagrass and Kentucky bluegrass during 90 days. However, treatments with either 20% or 30% AOSA were effective to develop root length of zoysiagrass but treatments with 20% AOSA were more effective than that of 30% AOSA mixtures to promote root length of Kentucky bluegrass at 60 days. In conclusion, considering all vital factors such as visible quality, root growth, organic matter content, and economical efficiency, was taken, it is recommended that a 20~30% mixture of AOSA with sand is good for the growth of zoysiagrass and 20% mixture Kentucky bluegrass." |
