| Abstract/Contents: | "Some preemergence herbicides result in root inhibition of both the target and non-target species. Nitrogen (N) leaching from established, healthy turfgrass has been reported to be low under normal conditions. However, the influence, if any, preemergent herbicides may have on N leaching and uptake resulting from root inhibition is unknown. Therefore, the objective of this study was to determine the effects of simultaneous fertilizer and preemergence herbicide applications on N uptake and leaching from Tifway 419 bermudagrass [Cynodon dactylon (L.) Pers. × C. transvaalensis Burtt-Davy]. This experiment consisted of 5 treatments and 4 replications, arranged in a randomized complete block design and was initiated on June 9th, 2017 at the Ft. Lauderdale Research and Education Center. Three preemergence herbicides and two controls were stablished as the five treatments evaluated on this study. A negative control (no-turf) was used to determine naturally occurring levels of N leaching in the absence of turf, pesticides, and fertilizers. A second control (turf) was used to evaluate nutrient loss under healthy turf conditions. The three preemergence selected for this experiment and their respective rates were oxadiazon (224 kg ha-1), prodiamine (1.17 L ha-1), and indaziflam (0.33 L ha-1), applied every other fertilizer application (every four months). Sprigs were planted on February 23rd on a new mixture of 90% sand and 10% peat. Normal management practices for fairway high grasses were performed according to BMP recommendations, including fertilizer [15-02-12 (N-P-K)] application at 49 kg ha-1 60 d-1 to turf plots. Leachate was collected as needed and analyzed for NO3-N and NH4-N. Tissue was harvested once each month and analyzed for N content determination. Roots were collected 4 and 8 weeks after treatment (WAT) (0-5 cm and 5-15 cm) and analyzed for length density and herbicide injury (1 to 6 scale; 1 = no symptom and 6 = most tissue is necrotic). Turf Quality (1 to 9 scale; 1 = dead turf, 6 = minimum acceptable turf and 9 = optimum turf) was assessed every other week. Total N concentrations peaked one week after application (WAA) and declined to concentrations lower than the negative control at three WAA. Rainfall events that occurred during the study contributed to N leaching. Turfgrass may provide an ecological benefit by reducing the amount of N that leaches naturally." |
