| USGA Summary Points: | The relationship among visual quality, growth rate, and NDRE of creeping bentgrass is linear and varies throughout the year. Guided machine learning will be used to create a decision support system tool to determine the rate of nitrogen fertilizer needed to meet visual quality and growth rate goals. Spatial variability of creeping bentgrass fairways were quantified throughout the summer from reflectance measurements to create site-specific management units for precision nutrient management. Variable rate nitrogen fertilizer application based on reflectance thresholds were demonstrated on a working golf course in Lincoln, NE. The NDVI variable rate application reduced variability and nitrogen applied by 30% compared to a constant and NDRE variable rate application methods. Further research is needed to validate the nitrogen fertilizer decision support system and to integrate the models into a user-friendly software for use by golf course superintendents. |
