Clipping volume: what the grass is telling you

Clipping volume is a rapid, practical measurement of grass growth that takes just minutes each day yet transforms how we make management decisions. This presentation covers why volume measurement works better than weight for routine tracking, how to interpret what normal and target clipvol values look like across seasons and for special events, and the practical applications that matter most—adjusting nitrogen based on actual growth, timing topdressing for organic matter management, preparing greens for tournament conditions, and understanding the variation from green to green. The underlying principle is simple: greenkeeping is about controlling growth rate, and you can’t control what you don’t measure. A few minutes with a bucket gives you data that turf managers have described as their most important metric—comparable to working without a weather forecast if they didn’t have it.
