감람석세사 배토에 따른 골프장 그린의 조류(Algae) 방제 효과 = Effects of Olivine Sand Topdressing on the Algae Control of Golf Course Green

다국어 초록 (Multilingual Abstract)

Algae which was commonly found on greens in golf courses had a bad influence on putting quality. Synthetic chemical fungicides could effectively control algae but also cause environmental problems. Olivine sand as the substitute of chemicals was tested for controlling algae of golf course greens. In the pond water treatment, the pond water with olivine sand was clean when compared to algae-polluted pond water with river sand. In the topdressing treatment, olivine sand topdressing was effective for controlling algae when compared to no sand topdressing, river sand topdressing and half olivine + half river sand topdressing. The reason why algae could not grow in the olivine sand was probably caused by lack of nutrition such as nitrogen and phosporous in the olivine sand of ore-law material. High temperature of quick drying water also represented the repressing effect of algae content and prevented the growth of algae after olivine sand topdressing.
