Fairways account for an average of 11.3 irrigated hectares on each of the 15,000+ golf courses in the US. Annual median water use per hectare on fairways is between ~2,800,000 and 14,000,000 liters, depending on the region. Conventional fairway irrigation relies on visual observation of the turfgrass, followed by secondary considerations of short-term weather forecasts, which oftentimes lead to “blanket” applications to the entire area. The concept of precision irrigation is a strategy to achieve water use reductions by making applications only where, when, and in the amount needed. The use of technology, such as soil moisture sensors and valve-in-head sprinkler control systems, can further enhance its application. Fairways have the most promise for water conservation through precision irrigation on golf courses due to their more intense management compared to roughs and larger area compared to greens and tees. Soil moisture sensors equipped with GPS can obtain georeferenced point data for creating soil moisture maps to identify variability, which may be useful for fairway precision irrigation. Previous research conducted in FL and MN has created soil moisture maps to demonstrate that variability within fairways can be excessive, but findings are limited to a few golf courses in these states, and only 1 to 2 fairways per course. To further investigate soil moisture variability at larger scales, a golf course fairway soil moisture mapping protocol was developed at the University of Minnesota in 2019. The protocol outlines standard procedures for golf course superintendents to collect georeferenced soil moisture data (% volumetric water content; VWC) with a commercially available, GPS-equipped, handheld soil moisture meter. The objective of this case study is to report fairway soil moisture variability findings from eight golf courses (four public and four private) in seven states (AZ, CO, FL, KS, MN, NH, and TX) that completed the protocol during 2019-2021. The courses exhibited a wide scope of turfgrass species and varieties, soil types, and irrigation systems and philosophies. Approximately 100-300 georeferenced soil moisture data points were collected per fairway using either a FieldScout TDR 300 with an external GPS receiver or FieldScout TDR 350 with an internal GPS receiver. All data at an individual course were collected the same day, and 7 to 14 fairways were considered depending on course. Cumulative rainfall and irrigation 7 days prior to data collections were recorded. Soil moisture variability was determined through summary statistics and ordinary kriging to create spatial maps. The mean, range, and coefficient of variation of soil moisture on fairways across courses were from 22.5 to 42.7 %VWC, 27.6 to 44.0 %VWC, and 7.6 to 39.6%, respectively. Spatial maps of soil moisture aided in visualizing the variability within and between fairways at all courses. Results suggest that soil moisture variability at large scales may be inevitable on fairways, regardless of climatic region and course characteristics, which further reiterates the need for advanced irrigation practices and technologies for water conservation via precision irrigation.
