Abstract

Earthworm cast occurred in surface of turfgrass in golf courses which affect turfgrass maintenance and golf play. In this study several survey of seasonal fluctuation of earthworm cast in different golf courses (Anseong, Gapyeong, Gunpo and Yongin in Gyeonggi province, and Geumjeong in Busan) was done. A number of earthworm, soil temperature and moisture of detection site of earthworm cast in each golf course were also done. Cast occurred in different golf courses are found mostly from April to November on turf surface and the cast number varied in different month as well as in golf courses. In the same golf courses, a number of detected cast was difference from individual sites. A number of cast and earthworm was correlated. Also, in higher soil moisture showed the higher cast density in different golf courses. Soil temperature and moisture of detecting cast ranging from $2.1^{\circ}C$ to $33.1^{\circ}C$ and 4.9 to 44.1%, respectively. In case of cast, soil temperature level lies in between $10-15^{\circ}C$ where the highest soil moisture was 25%.

골프장 잔디위로 배출되는 지렁이 분변토는 잔디관리와 경기진행에 있어 피해를 주고 있다. 본 연구는 골프장에서 지렁이 분변토의 발생변화를 시기별, 지역별(경기도 가평, 군포, 안성, 용인, 부산 금정)로 조사하였으며 분변토 발생량이 많은 지역과 없는 지역을 구분하여 토양 수분과 토양온도 및 지렁이 개체수를 조사하였다. 지렁이 분변토는 4월부터 11월까지 년 중 골프장 잔디에 발생하고 있었으며 골프장 별 및 시기별에 따라 차이가 있었다. 동일골프장에서 조사 지역에 따라 차이를 보였다. 분변토 발생량과 지렁이 수는 양의 상관관계가 있었으며 분변토 발생이 많은 지역과 없는 지역간의 토양 온도는 차이가 없었으나 토양수분은 분변토 수가 많은 지역에서 높았다. 지렁이 분변토는 토양온도 $2.1^{\circ}C$에서 $33.1^{\circ}C$의 범위에서 확인되었는데 주로 $10-15^{\circ}C$ 사이에 발생하였다. 또한 토양수분은 4.9-44.1% 범위 내에서 발생하였는데 주로 25% 내외에서 발생량이 많았다.
