Nowadays, there are increasing demands of golf courses and it is necessary to make more golf courses than the present. To do this, we need to improve the environmental problems with the regional inhabitants, and it is said that the first thing to be considered in developing any golf course in Korea is to preserve the environment. In this context, the purpose of this study is to set forth several design factors to lessen the negative impacts which are accompanied with the development of golf courses. 1. The present conditions of golf courses in Korea Many new golf courses have come into being, particularly since the late 1980s, and now, in the year of 1997, over one hundred of golf courses are doing their business, yet the number of golf course is still less than required. So far, over a half of them have been made in the vicinity of Seoul on account of various reasons, and this has adversely affected on our natural environment. This unreasonable development of golf courses has caused serious water pollution, landslides and the other problems. Also, the topography of Korea is not good for golf courses. Although the demands of golf courses are increasing, the suitable sites for them are very limited, and therefore it is sometimes unavoidable to make golf courses on steep hills. Consequently, in designing golf courses in Korea, the most important thing is the balance between natural environment and artificial environment. 2.Eco-friendly golf course design factors 1) The concept of eco-friendly golf courses Ecologically sustainable and sound golf courses which are made by eco-friendly approaches 2)Basic conditions of eco-friendly golf courses (1)The most suitable sites (2) Conservation of existing ground as much as possible (3)Proper use of agricultural chemicals which have great impacts on the environment (4) Reasonable use of fertilizers (5) Developing a specialized fertilizer only for grass (6) Adaptation of organic agriculture (7) Improvement of grass sorts (8) Establishing reservoirs for purifying the water from golf courses 3) Eco-friendly golf courses (1) Location-Enough area /Gentle slope/Winding ground/Including lakes or streams /Not crossing wind's main direction Facing south or southeast /Suitable soIl for grass /Good drainage /Low level of underground water (2)Course layout and design -Consideration about existing contours as much as possible -Adaptation of Scotish design trend -Various holes' configuration -Consideration toward surrounding landscapes -Reducing grass areas -Giving buffer zones -Adapting computer methods in the process of site analysis and design (3) Eco-friendly considerations in constructing and managing golf courses -Protection of wildlife -Reuse of existing forests and preservation of topsoil -Renovation of old-fashioned courses -Reducing grass areas -Purification of water -Standization of management -Strict regulations against chemicals -Recycling organic materials -Through separation of the water inside golf courses and out of bounds -Getting proper construction works done in a due time 4.Eco-friendly considerations from a viewpoint of cultural environment 1) Well-matched landscape design and events planning 2) Implement of identifications and awarding systerns 3)Acknowledgement of superintendents' qualitications in the maintenance of golf courses 4)Increasing public golf courses and keeping good relationships with the neighbors near golf courses Key words: Pro-environmental development, Golf course.

The objective of this study is to present management methods for Korean golf courses to achieve fast green that satisfies international golf tournament standards during an official golf tournament. The results of both the research and the comparative study on putting green management of 24 tournaments hosted in Korea and 12 tournaments hosted in overseas countries in 2002 are as follows: 1. As for the putting greens in Korean and foreign golf courses where official golf tournaments were held, Korean of official golf tournaments were mainly opened in two-green system golf courses contrary to the foreign cases, and the average size of the greens in Korean golf courses was shown to be greater than that of foreign golf courses to some extent, although there was no difference between the types of turf varieties. 2. Results have shown that unlike foreign golf courses, Korean golf courses were managing putting greens by using greens mowers mostly for general (non-tournament) management, and elaborate rolling attempts failed during official tournament flay week because of an insufficient number of rollers to be input. Therefore, Korean golf courses are required to make efforts to secure 21-inch working-behind greens mowers equipped with tournament bedknifes and 11 blades, which is the greens mowing equipment for professional tournaments, and rollers above all things in order to achieve fast green during tournament play week 3. In attempting to achieve green as fast as that of foreign golf courses, Korean golf courses need to consider the method of performing mowing at 3.0mm height or less with greens mowers for professional tournaments. This needs to be done more than two times, followed by a continuous practice of rolling for proper management.

This study was carried out to investigate the utilizing of cool-season turfgrass in areas, excluding greens, of Korean golf courses. Data collected from 120 golf courses were subjected to frequency and T-test analysis using SPSSWIN. The results obtained were as follows: 1) seventy eight golf curses were utilizing cool-season turfgrass in areas except of the greens. At thirty five golf courses (46.0%) of them, the area utilized appeared tee, green collar, green approach etc. (tee>green collar>green approach). At 37 golf courses(48.7%), a mix of Kentucky Bluegrass and Perennial Ryegrass was utilized and the ratio of the mix was 70:30(v/v). At 57 golf courses(76.0%), seed sowing was utilized. 2) In Korean golf courses, the cognition of utilizing cool-season turfgrass depended on the existence of the practice. The cognition of the experienced was more´ affirmative´ than that of the inexperienced. 3) In the experienced, the preference was determined by turfgrass quality and good appearance and recuperative rate of cool-season turfgrass. In the inexperienced, the preference was determined by turfgrass quality god appearance. 4) The experienced recommended the mix of Kentucky bluegrass and Perennial Ryegrass. 5) It seems that the golf courses having used cool-season turfgrass have difficulties in the maintenance in summer while the golf courses without using cool-season turfgrass have difficulties in the maintenance in summer and the selection of turfgrass variety.

The purpose of this study is to discovered assessment items for improving athletic efficiency and management of golf courses. Through this, the study intended to provide basic data for creating competitive golf courses and management. Important assessment items were selected by inducing preliminary assessment items and conducting a preliminary survey and a main survey for specialists through a theoretical study. For the survey results studied, reliability and average value for importance were calculated using SPSS/PC Window Release 12.0. As assessment of importance by assessment area, in athletic efficiency assessment, course management level was the highest, followed by fairness of games and operation of games. In management assessment, importance of service level, information management, facility management, management of game assistants, etc. were high. As assessment of importance by assessment item, it was found that 'variety of golf shot' and 'the length of a course' were important in course layout. Also 'start interval among teams' and 'disturbance of play' were assessed as important items in game operation, while 'fair reservation' and 'rounding rotation time' were important in fairness of games. In addition, in information management, 'kind service of golf course staffs' and 'prompt reservation and notification' were found to be important assessment items. In facility management, all assessment indexes were over 4.0, which means all of them are important for quality of golf course and competitiveness. In membership service, 'appropriate price of goods for sale' and 'service for members' were relatively important assessment items. Further, in management of game assistants, 'qualifications and skillfulness of game assistants' was assessed as a very important index. Although the current study only selected important items to assess excellent golf courses, it is necessary to apply the study results to the actual sites and verify them for golf course both at domestic and abroad.

A study was carried out in order to elucidate utilization of agochemicals in golf courses scien-tifically. The analysis of amounts of agrochemical used in golf courses from 1991 to 1996 which were reported to government are ;Despite of increase of golf courses, the amounts of agrochemicals decreased from 1992 as turning point. The decrease of utilization of insecticides and herbicides made it possible. In fungicides, thiopanate-methyl WP, polyoxine D. thiram WP and iprodione WP were used much in general and their utilization ratios were high. In recent year, as fungicides for Pythium blight and large patch, oxapro WP and pencycuron WP's amounts of utilization increased, but utilization ratios were under 70%. In insecticides, penitrothion OL's quantity consumed and utilization ratios were the best, but showed tendency of decrease as registration of agrochemicals for turfgrass expanded. In herbicides, bensulide OL, napropamide WP, MCPP SL were used much and their utilization ratios were high. In recent year, flazasulfuron WP's amounts of utilization and utilization ratio increased relatively. Key words: Agrochemicals Golf courses, Insecticides, Herbicides,Fungicides.

This Study was carried out to investigate on the environmental effects of golf courses and to find a solution to the negative effects in Korea. The results were ai follows. 1. There were 152 golf courses opened in December 2000. 113 golf courses were member-ship and 39 golf courses were public. Users (golfer) were over 12,000,000 in 2000. 2. Total area of golf courses was 0.8% as compared with total area of farmland in 1999. Total amount of agricultural chemicals used in golf courses was 0.3% of total amount of agricultural chemicals used in Korea. The remaining amount of agricultural chemicals in golf courses tested were almost below the permitted limits. 3. Recently, total amount of fertilizers in green decreased 5~7g/$m^2$/year as compared with the recommended. 4. The control by antagonistic microorganisms and the fertilizing of the organic matter or the organic fertilizer were effective to decrease the amount of agricultural chemicals used. To success the control of microorganisms, active antagonistic microorganisms had to be applied over the recommended dose eve교day. Though fertilizing of organic fertilizer, slow release fertilizer, was effective to suppress dollar spot, necrotic ring spot. fungicides were required as a supplementary means when disease symptom was very heavy. 5. Zoysiagrass was fertilized intensively from May to August. Cool-season grasses were fertilized intensively from March to May and September to October. The fall fertilizing of Zoysiagrass was carried out to the begining of October. The fall fertilizing of cool-season grasses were carried out to the end of November or the begining of December. The fertilizing amount of Zoysiagrass was 10g/$m^2$/year. The fertilizing amount of bentgrass was 25~27g/$m^2$/year.

In eight golf courses of southern area fair way soil profile was investigated for soil physical, chemical properties, and root distribution. These were carried out only A horizon(lScm depth) in one golf course. Soil series was all different, Leaching to lower horizon was greator in order of Mg=$NO_3$> $NH_4$=Ca> K. Organic matter content was higher in B horizon than A in three golf courses. Soil phosphorus appeared to more down greatly in two golf courses. Soil pH was higher in lower horizon of all places. Such pH increase with depth seemed to he related with mineral leaching, Among the horizons of all golf courses BC showed significant correlation with K (EC =0.1025K +0.0157, r=0. 8012 p=0. 001 n=20). Both Fe and Mn were higher in A horizon.

Field surveys were conducted to assess the occurrence and diversity of plant-parasitic nematodes (PPNs) in golf courses and athletic fields across Maryland, USA, during 2022 and 2023. A total of 28 golf courses and ten athletic fields were surveyed, revealing the prevalence and abundance of 13 PPNs taxa in the region. Criconemoides was identified as the most prevalent (94.9%) and Tylenchorhynchus as the most abundant (2.3) across all samples. Central golf courses (west side of the Chesapeake Bay) exhibited a high prevalence of Criconemoides and Tylenchorhynchus, while Eastern Shore golf courses and athletic fields displayed a higher prevalence of Helicotylenchus and Criconemoides. Further, Belonolaimus longicaudatus was reported for the first time from turfgrass in Maryland, raising concerns due to its potential to cause severe damage on both cool- and warm-season turfgrass. Biodiversity analysis indicated that richness (R²) was higher in athletic fields, while diversity (H') and evenness (J') were significantly greater in golf courses. This study provides baseline information for monitoring PPNs distribution in Maryland and also for the development of effective nematode management approaches in turfgrass ecosystems.
