Fairy ring is a frequently reported disease of turfgrasses worldwide, and necrotic or severely injured grass are observed in those turf sites exhibiting type-I fairy ring symptoms. The objective of this research was to characterize soil chemical and physical properties at two soil sampling depths (0.5 cm and 3.0 cm) at a turfgrass site exhibiting type-I fairy ring symptoms. Soil samples were obtained from a perennial ryegrass (Lolium perenne L.) golf course fairway at one sampling date in the summer when environmental conditions were most conducive to the appearance of severe type-I fairy ring symptoms. At both soil depths, soil analysis indicated that concentrations of ammonium-nitrogen, potassium, and sulfur were statistically higher in soil underlying necrotic or bare zones versus soil in healthy turfgrass zones. At both soil depths, soil electrical conductivity was statistically higher, and volumetric soil water content was statistically lower in necrotic zones versus soil under healthy turfgrass. At both soil depths, total nitrogen, magnesium, calcium, cation exchange capacity, and organic matter content were not statistically different among necrotic and healthy turfgrass zones. Soil pH was statistically higher in the necrotic zone versus soil under healthy turfgrass at only the 3.0 cm soil sampling depth. Comparing soil properties within the necrotic zone, only potassium and electrical conductivity was statistically higher at the 0.5 cm depth compared to the 3.0 cm depth. Although most soil information was considered very similar at both sampling depths, soil sampling at the 3.0 cm depth would be a more practical or easier method for turfgrass managers. At either soil sampling depth, the necrotic zones of type-I fairy ring areas in turfgrass were most likely associated with a combination of direct and indirect effects of the basidiomycete fungi on soil chemical and physical properties in the turfgrass root zone.
