USGA Summary Points:Temperature, relative humidity and evapotranspiration were the key weather factors for estimating bentgrass growth. Foot traffic, nitrogen rate and soil moisture were weakly correlated with bentgrass growth. However, model accuracy substantially increased when these variables were included. A data-driven statistical model using the machine learning random forest algorithm can accurately predict bentgrass yield. However, the model was only effective for the location where the model was built, suggesting that individual golf courses need to build customized growth prediction models to manage nitrogen adaptively. This can be accomplished by collecting and recording clipping volume for at least one year. The machine learning random forest algorithm appears to be very helpful for guiding N application decisions, and when it was used over a two-year period on two different root zones, it resulted in acceptable turfgrass performance with about 50% less N fertilizer usage than the method that recommended the most N fertilizer (PACE Turf method) and about 30% less fertilizer than the traditional way that golf course superintendents schedule N applications.
