| Abstract/Contents: | "Turfgrass managers often use compost to remediate soils decimated by construction activity, traffic-induced compaction, or neglect prior to establishing the area to turf. Many compost options exist, and depending on their source material and curing time, can have highly variable nutrient levels or salt content. Due to compost variability, methodology to quickly determine acceptable thresholds of nutrient and electroconductivity (EC) levels needs further investigation. This trial was conducted at the Iowa State University Horticulture Research Station near Ames, IA, in a hoop house. Design was a randomized complete block with five replications. Turf treatments were perennial ryegrass (Lolium perenne L.) cultivars Accent (salt-sensitive) and Spyglass (salt-tolerant) seeded at 39 g m-2. Soil treatments were native soil:compost ratios of 100:0, 80:20, 70:30, 60:40, 50:50, 40:60, and 0:100 by dry weight. Main compost sources were dairy manure, equine manure, and lawn/leaf waste. Leachate was collected weekly via pour-thru extraction to measure pH (data not shown), EC, and nitrate (NO3-) content. Percent green cover was measured by digital image analysis. Hypotheses were that compost content of 30%+ (salt-sensitive cultivar) and 50%+ (salt-tolerant cultivar) will result in reduced turfgrass establishment (percent cover) and that increased compost content will increase NO3- and EC levels in collected leachate. Nitrate and EC levels declined over time and compost percentages over 30% had EC above acceptable level of 4 dS m-1 through 21 days after seeding (DAS). Treatments were not different by percent cover through 14 DAS. At 16-28 DAS, 100% soil had the lowest percent cover but ended the trial similar to all other treatments. The 100% compost treatment had lower percent cover than other compost-containing treatments during 16-21 DAS. The salt-tolerant cultivar had lower percent cover at 21 and 23 DAS; both cultivars were similar on all other rating dates." |
