| Abstract/Contents: | "Shade on turfgrasses leads to leaf elongation and thinning of the turf surface. Management of shaded turf areas is affected by many variables including air movement, the percent shade, the type of shade and time of day. Strategies which have been investigated include the use of growth regulators (Steinke and Stier, 2003; Wherley et al., 2005) and different sources, forms and rates of nitrogen (Goss et al., 2002). The aim of these investigations is to alter plant growth in a way that reduces leaf elongation and reduces loss of surface quality (Beard, 1997). Nitrogen is required for maintaining sufficient turfgrass quality since it is an essential component of many plant compounds required for growth and development (Fry and Huang, 2004). Nitrogen movement into turfgrasses has had minimal investigation and no research has looked at uptake of nitrogen sources in shaded conditions. In full sun (FS) conditions using perennial ryegrass, Bowman and Paul (1992) found that KNO3, (NH2)2CO and (NH4)2SO4 entered at a similar rate when applied to the leaf. This research showed that the partitioning of N varied between leaves and roots. Henning et al., (2009) found a similar result on creeping bentgrass while Stiegler et al., (2009) found that (NH2)2CO was taken up in greater amounts in comparison to other N sources also on creeping bentgrass. It is unknown how these fertilizers act in shaded conditions, however, and the objective of this research was to investigate if there is a difference in nitrogen uptake from foliar fertilizer applications to shaded creeping bentgrass (Agrostis stolonifera)." |
