Abstract/Contents: | "Compost incorporation can improve soil quality, however, the impact on the N fertility requirements of turf is not well known. This study evaluated the N fertility response of Kentucky bluegrass turf grown on soil amended with three composted wastes at two amendment rates. Food and leaf composts and a municipal solid waste co-compost (MSWC) were incorporated at rates of 0.05 and 0.10 m3 m-2 into an eroded sandy loam (fine-loamy, mixed, mesic Typic Hapludult). Plots were seeded to Kentucky bluegrass (Poa pratensis L.) in September 1993 and fertilized at N rates of 0, 2.45, 4.90, 7.35, and 9.80 g m-2 in November 1993, May 1994, and April and October 1995, and April 1996. Leaf and food compost amendment improved turf cover compared to unamended plots, and cover was maximized at 4.90 g m-2 of N. Establishment was delayed up to 7 months with MSWC, likely to due to its high C:N ratio (42). A rate of 2.45 g N m-2 on plots amended at 0.10 m3 m-2 was sufficient to achieve the highest turf quality; N fertility of 7.35 g m-2 on plots amended at 0.05 m3 m-2. Turf quality on compost plots receiving no N fertility was similar or better than the turf quality of unamended plots receiving 9.8 g m-2 of N. Thus, it is feasible to expect amendment of landscape soils with a quality compost to substantially reduce the need for N inputs on turf." |
