| Abstract/Contents: | "Nutrients applied according to the best management practices (BMPs) for Florida golf courses have very little opportunity to contribute to nonpoint source pollution when applied to healthy turfgrass. Some pre-emergent herbicides are documented to inhibit root growth, which may increase nutrient leaching even on healthy turfgrass. The objective of this research is to determine the effects of pre-emergent herbicides on nitrogen (N) and phosphorous leaching and nutrient uptake of tifway 419 hybrid bermudagrass [Cynodon dactylon (L.) Pers. x C. transvaalensis Burtt-Davy]. Treatments were arranged in a randomized complete block design with four replications and included a no-turf control, a no-herbicide control, oxidiazon (224 kg ha-1), prodiamine (1.17 L ha-1), and indaziflam (0.33 L ha-1). Bermudagrass sprigs were planted on February 23rd on a mixture of 90% sand and 10% peat and data collection began June 1, 2017. Nutrients were be applied to all plots every two months using a 15-5-15. Leachate was collected as needed and analyzed for NO3-N, NH4-N, and orthophosphate. Tissue nutrients, thermal images, and NDVI were measured every two weeks. Roots were collected 4 and 8 weeks after treatment and analyzed for root length, diameter, dry weight, and visual assessment for abnormal growth. This study has a potential impact of validating that current BMPs are appropriate even under the conditions of root inhibition by pre-emergent herbicides. Should pre-emergent herbicides result in N and P leaching, best management practice would be amended accordingly." |
