초록

The construction procedures and artificial turf maintenance program on golf course
definitely influence on the distortion of its environment. Soil microbial communities in
soil profile were affected directly by those practises on turf areas. In Jeju island, the
environmental impact assessment has been required to apply the first quality class
granular activated carbon(GAC), which has a high absorbent character to agricultural
chemicals, on the soil profiles of golf green system to reduce the pesticide leaching to
ground water. This research was carried out to analyze the changes of microbial
communities and chemical properties on soil profiles where GAC had been applied at
the construction stage at two golf courses in Jeju. The changes of soil microbial
population and chemical properties associated with construction methods of soil profile
and agrochemical management program were analyzed by monthly at the surface and
sub-soil profiles during April through October, 2007. The total numbers of bacteria and
fungi, soil moisture content, soil physio-chemical properties were measured on greens
and fairways of the both golf courses with different GAC treatment on the green and
fairway soil profiles. The results showed that GAC had positive effects on the water holding capacity, pH
and EC, however, it did not improved the holding capacity of available nutrients
NO3
-,NH4
+, and phosphorus by its sorption phenomenon. In microbial count test, the
total numbers of bacteria and fungi showed a great variation during sampling dates.
That may directly relate to the agrochemical application, however, the ratio of total
bacterial number versus total fungus number showed a constant value on a sub-soil of
15~30cm depth. Thus, the construction method of GAC in soil profile, and application of
fertilizer and pesticide, both impacted on the changes of microbial population. It's means
that the construction method of soil profile and turf management using agro-materials
might greatly affect on the turfgrass culture and the environment of golf course.
