| Abstract/Contents: | "Precision turfgrass management (PTM) currently relies heavily on mapping technologies to identify variability for site-specific applications of management inputs. Despite recent advancements of mapping technologies for turfgrass, a number of potential factors have inhibited widespread adoption of PTM. While focus continues towards mapping technologies, the turfgrass manager's knowledge of variability may be overlooked and underutilized for PTM implementation. Demonstrating the extent of knowledge that turfgrass managers encompass regarding variability, and how they may already be applying this knowledge to their management practices, could 1) facilitate low-tech mapping strategies, 2) assist in improving current mapping technologies, 3) justify the value of current mapping technologies, and 4) warrant the need for additional mapping technologies beyond what is presently available. A case study was conducted with assistant and head golf course superintendents in Minnesota (12 total) using a qualitative GIS approach (interviews, spatial maps, and photo elicitation) aimed at understanding their knowledge of variability within fairways. One fairway from each participants' golf course was randomly selected for use in the study. Initial and follow-up interviews were conducted utilizing a semi-structured interview guide and audio recorded to ensure accuracy of responses. Initial interviews with each participant took place at the predetermined fairway on their course to gain an in-depth understanding of their perception of variability within the fairway. Two paper copies of the fairway's digitized boundary were provided for participants to draw turfgrass quality (i.e. visual color, density, etc.) and soil moisture zones (e.g. areas of high, moderate, and low) based on their knowledge and experience. Immediately after initial interviews, turfgrass quality [normalized difference vegetation index; (NDVI)] and soil moisture (volumetric water content; VWC) were measured across the fairways that resulted in ~100-120 georeferenced data points (utilizing a GPS on the soil moisture measuring device). Georeferenced NDVI and VWC data were imported in ArcMap and interpolated via ordinary kriging to create continuous surface maps of each variable. Standard deviation-based legend classifications were used to highlight areas of high, moderate, and low values within the fairways. Follow-up interviews with each participant were conducted 1-3 weeks later in their office to gain an in-depth understanding of how they compared their hand-drawn maps with interpolated maps, as well as their perceptions about the value of mapping technology after comparing maps, limitations to mapping technology at their course, and how to increase adoption of PTM in the golf course management industry. Audio recordings of all interviews were transcribed verbatim and imported into ATLAS.ti for coding and thematic analysis. Hand-drawn maps were digitized into ArcMap for statistical comparison between hand-drawn and interpolated maps. Interview responses, hand-drawn maps, and interpolated maps were triangulated to further explore and validate findings." |
