Kentucky bluegrass ( Poa pratensis L.) and tall fescue ( Festuca arundinacea Schreb.; syn., Lolium arundinaceum Darbyshire) are cool-season grasses commonly used for lawns in temperate regions of North America. However, these grasses can be
, increased salinity tolerance is a priority of a number of C 3 and C 4 turfgrass improvement programs ( Horst and Beadle, 1984 ; Marcum et al., 1998 ; Qian et al., 2000 , 2007 ). A major turfgrass species is kentucky bluegrass (KBG; Poa pratensis L

The practice of applying fertilizer in liquid form to turfgrass has become popular in the commercial lawn care industry, but foliar bum may become a problem following such applications. Fertilizer bum, ranging from leaf tip browning to bleaching of the entire leaf blade may result when a plant suffers physiological drought caused by an excess of soluble salts, either on the foliage or in the soil solution (2, 9). Researchers have reported that increasing levels of soil moisture stress may cause more severe fertilizer burn than nonstress conditions (4, 5, 6).
Alkaline soils in Nebraska reduce crop yields and lower aesthetic values of ornamentals and turf (2). Chlorosis associated with alkaline soils occurs in many plants and influences plant growth and development by reducing photosynthetic efficiency (1). Data for turfgrass species and cultivar growth at high pH would be useful.

bentgrass is competitive with other cool-season turfgrasses at higher mowing heights (7.5 to 10 cm) and often spreads into surrounding areas of Kentucky bluegrass ( Poa pratensis L.) ( Davis, 1958 ). Creeping bentgrass is considered a weed in these
Snowmobiles used as recreational vehicles on winter dormant turfgrass areas have become an increasingly widespread activity in recent years. Because of this recreational demand, certain portions of or routes within parks, golf courses, and other large turfgrass areas are being set aside for winter snowmobile use. Serious damage to turfgrasses occurs in some situations, whereas in others, there has been no significant damage. To the best of our knowledge, there are no published reports of studies regarding snowmobile traffic effects on turfgrasses (3). Thus, the objective of this investigation was to assess the effects of 6 intensities of snowmobile traffic on 2 winter dormant turfgrasses covered with 5 depths of snow.
containing wood, bark, and leaves. The two cool-season turf species were ‘Kentucky-31’ tall fescue seeded at 3.6 kg·ha −1 and ‘Moonlight’ Kentucky bluegrass ( Poa pratensis ) seeded at 1.2 kg·ha −1 . On 27 May 2003, the warm season turf plots were sprigged
