Abstract/Contents:"Little information is available on the persistence of turfgrass under returned grass clippings. The purpose of this field study was to analyze rooting response of tall fescue turfgrass to different clipping managements. Three treatments, included two cultivars, (Noria and Safari) and two fertilization levels (100 and 200 kg ha-1 N y-1), and two clipping managements (returned or removed) were compared in a split plot randomized complete block design. From August to February[,] core samples were analyzed to determine parameters of rooting response on thatch layer and three soil levels (0-30, 30-80, and 80-150 mm of depth): 1. root weight density, 2. root length density, and 3. root diameter. Plots were regularly mowed when the height of 80 mm was reached, and they were maintained at 60 mm height, using a conventional rotary mower machine with clippings removed or recycled. In two soil levels, (0-30, 30-80) a consistent cultivar effect was found. The turf-type cultivar (Safari) respect to the forage-type cultivar (Noria) was characterised by an [a] higher root weight density. At the same depth intervals a detrimental effect on root density (length and weight) was found on the variety Safari with the increase of nitrogen fertilization rate from 100 to 200 kg ha-1 y-1. Returning clippings resulted in a severely[severe] root density reduction. A depletion of about 45% ad 35% of total root density and root length density was observed under returned clippings. Moreover, the difference between the upper and the deeper level was higher when clippings were removed. Root diameter appear to be not affected by clipping management, even if at the upper level of soil profile (0-30) a reduction of root diameter occurred in consequence of clipping release. In all cases the most negative effect on tall fescue root growth was caused by the high levels of nitrogen fertility (200 kg ha-1 y-1) combined with clipping release on the variety Safari."
