| Abstract/Contents: | "Objective tests are not widely used to guide fall N fertilization of turfgrasses, and N is applied at predetermined rates regardless of plant-N status. This study was conducted across 3 yr in Connecticut to determine if fall verdure concentrations of total N, dry-tissue extractable nitrate (NO3)-N, and fresh sap NO3-N could guide fall N fertilization for a mixed-species, cool-season turfgrass lawn. Field experiments were set out with varying fall N rates and verdure samples were collected weekly in October and November. Verdure tissue-N test concentrations in response to N rates were analyzed with polynomial (quadratic or cubic) and linear-response and plateau (LRP) models. Models were significant (P < .0001) for all tissue concentrations in response to N rates and estimates were comparable between models. When referenced to expected responses from the commonly recommended fall N rates of 24.5, 49, and 98 kg ha-1, there would be no need for N fertilizer when concentrations of fall verdure total N are ≥22, ≥25, and ≥30 g kg-1; dry-tissue extractable NO3-N are ≥119, ≥193, and ≥840 mg kg-1; and fresh sap NO3-N are ≥94, ≥115, and ≥171 mg L-1, respectively. Variability of the verdure tissue-N tests was no greater than most routine soil and tissue tests currently used to monitor nutrient status in turfgrasses. The results suggest that verdure tissue-N tests have potential in guiding fall N fertilization of cool-season turfgrass lawns." |
