| Compound fertilizer contained slow release nitrogen was used at golf course management because of promoting turfgrass growth and decreasing fertilizing labor. But, it was hardly published about turf grass growth by its effect and form like isobutylidene diurea(IBDU) and methylene urea(MU) in golf course management of Korea. This study was conducted to investigate the effect of compound fertilizer contained slow release nitrogen such as IBDU and MU on creeping bentgrasss and the change in nitrogen in the root zone after application of fertilizers at AM turfgrass research institute with soil analysis, chlorophyll content index, leaf area index and dry weight during 5 months from July to december in 2007 year. Fertilizer treatments were designed as following; non-fertilizer(NF), straight fertilizer(CF), treatment 1(MU), treatment 2(IBDU 1), and treatment 3(IBDU 2). The every treatments were arranged a randomized complete block design with three replications. Results obtained were summarized as follows: As relative to time after N fertilizers application, ammonium and nitrate in soil were increased, but T-N was decrease. $NO_3$-N and T-N content of slow release fertilizer(SRF), the treatment MU, IBDU 1 and IBDU 2, in soil was higher than that of CF, and the change of ratio of available N and T-N by elapsed time after fertilizing SRFs and CF was higher about 5% in root zone of SF to l5days, but in root zone of SRF from 30days about $5{sim}10%$. Compared with NF, the turf color index was increased 6.5%, 6.7%, 5.9% and 5.5%, respectively, the chlorophyll content 33.2%, 38.4%, 35.1% and 37.1%, the dry weight 76.2%, 77.7%, 69.5 and 72.3% and shoot number 28%, 52%, 56% and 51%. The chlorophyll content index of MD, IBDU 1 and IBDU 2 was increased $2.6{sim}5.2%$ than that of CF, shoot number $18{sim}22%$ but turf color index and dry weight was analogous to that of CF. These results showed that the SRF application was supplied nitrogen for a long time in root zone by increasing an available nitrogen, and so bring turf growth such as chlorophyll content and shoot number in creeping bentgrass. |
