Abstract/Contents: | "Current turfgrass fertilizer recommendations do not account for plant-available soil N mineralized from labile C fractions. The Solvita Soil CO2-Burst (SSCB) test can measure mineralizable C via soil CO2 respiration. This study was conducted across 3 yr (2014-2016) in Connecticut to determine: (i) if SSCB-C concentrations are correlated to responses from predominately Kentucky bluegrass (Poa pratensis L.) and tall fescue [Schedonorus arundinaceus (Schreb.) Dumort.] lawns, and (ii) the probability of turfgrass responses being equal to or greater than responses from common urea rates in relation to SSCB-C concentrations. Randomized complete block design field experiments were set out with 23 rates of organic fertilizer (0-2000 kg N ha-1 yr-1) and four different rates of urea (50, 100, 150, and 200 kg N ha-1 yr-1). Yearly spring soil samples were analyzed for SSCB-C concentrations and correlated with turfgrass responses. Growth and quality responded positively and linearly (P < 0.001) to SSCB-C concentrations, but variability was high and correlations were relatively weak. When spring soil SSCB-C concentrations were ≥91, 113, 166, and 211 mg kg-1, there was a ≥90% probability that overall combined responses across species and variables would be equal to or greater than responses obtained from urea rates of 50, 100, 150, and 200 kg N ha-1 yr-1, respectively. The SSCB test has promise for predicting the probability of soils supporting turfgrass whose performance equals or exceeds benchmark values. This would be helpful in guiding N fertilization, but high variability within the test may limit its predictive ability." |
