In measuring the performance of the bowling green there are visual and functional factors to consider. Now that we've studied the visual clues we move on to the functional ones in earnest.

This property of sportsturf is closely associated with the physiology of the individual grass plants we looked at in an earlier series and also with bowling green performance, as it influences green speed and trueness.
