Earthworm Composition and Seasonal Population Structure in Different Korean Golf Courses

Triazole Fungicides Sensitivity of Sclerotinia homoeocarpa in Korean Golf Courses

Chemical management of dollar spot in turf may lead to the development of Sclerotinia homoeocarpa populations with reduced fungicide sensitivity. The objective of this study was to investigate resistance of S. homoeocarpa isolates to triazole fungicides and to test cross-resistance among three triazole fungicides. A total of 66 isolates of S. homoeocarpa were collected from 15 golf courses acro...

Seasonal Variation of Earthworm Abundances and Biomass in Natural Forests and Plantations (North of Iran)

Soil productivity and plant growth are usually affected by biological activities of earthworms. The objective of this study was a comparative evaluation of earthworm abundances in 20-year-old plantations of Alder, Oak, Maple and Cypress with the adjacent natural mixed broad-leaved deciduous forest in the Caspian region of Iran. In this research one sample plot, each 1 ha; was selected in every ...

Fairway Grasses for Midwest Golf Courses

Kentucky bluegrass can produce quality fairways in the Midwest if it is not mowed too short. Keep track of research. Climates vary widely across the Midwest, complicating the choice of fairway turf grass species. New epidemics of gray leaf spot have weakened the popularity of perennial ryegrass, long a preferred fairway species in many parts of the Midwest. Cultivars are available that accentua...

Changes in Urine Osmolar Composition seen in Different Age Groups in the Local Korean Population

Due to their unique living conditions and dietary habits, the Koreans' renal function model may be different from that of the Western people. About 40 years ago, a researcher reported that two thirds of the urine osmolality in Koreans was contributed by NaCl, while less than 1/3 by urea. It is known that the Koreans' daily consumption of NaCl is higher while their protein intake is lower, compa...
