Effectiveness of grass barriers and vegetative filter strips (FS) for reducing transport of sediment and nutrients in runoff may depend on runoff flow conditions. We assessed the performance of (1) switchgrass (Panicum virgatum L.) barriers (0.7 m) planted above fescue (Festuca arundinacea Schreb.) filter strips under interrill (B-FS) and concentrated flow (CF-B-FS), and (2) fescue alone under ...

Grazed pastures represent a potential source of nonpoint pollution. In comparison to other nonpoint sources (e.g., rowcropped lands), relatively little information exists regarding possible magnitudes of pollution from grazed pasture; how that pollution is affected by weather, soil, management and other variables; and how the pollution can be minimized. The objective of this study was to assess...

Infrequently mowed grass areas on institutional grounds and golf courses can reduce mowing costs impart a natural appearance to the property. However, weed encroachment into these compromise aesthetic appeal of stand increase associated with control. The objective this 2-yr field study was determine influence species frequency cover quality. Six or mixtures were established from seed subjected ...

unshaded sites in southern USA when exposed to high summer temperatures (Van Santen and Sleper, 1996). The design of agroforestry systems requires a thorough understandNeither orchardgrass nor tall fescue had significant ing of biological interactions that might complement or constrain yield reduction in pots exposed to 50% shade, and orproduction. The objective of this study was to examine eff...

Application[Editor 321]  of biotic growth regulators (e.g. humic components) and appropriate mulches is recommended to improve turfgrass quality especially in arid andsemi-arid climate zones. However, limited number of studies have investigated their effect on lawn establishment. To investigate the effect of humic acid (HA) and selected mulches on characteristics of Festuca arundinacea in its p...
