An average of six passes were performed each traffic day. A pass consisted of driving the simulator down the length of the overall plot along 0.3-m centers over the width of the overall plot. The plots were evaluated after traffic treatments and recovery periods for quality, density, color, percentage living turfgrass cover, percentage topdressing visible, and surface hardness. One traction assessment was taken on 15 May 1997. Quality, density, and color .
Turf quality is an overall visual rating of turf color, density, and texture.
Turf density and retention of a vegetative mat or thatch were considered more important than color when rating turf quality of treatments that received traffic. Turf density was a visual estimate of plants per individual plot area. Traffic tolerance was assessed by visually estimating quality and percentage turfgrass cover. Turf cover and percentage topdressing showing . Percentage living turfgrass cover is the most important parameter for evaluating the detrimental effects of traffic on athletic turf.
