GP and clipping volume in action

Growth potential (GP) and clipping yield are being used by more turfgrass managers around the world to gain more control of turf growth and to improve surface performance. Growth potential provides a reasonable estimate of turfgrass nitrogen needs and clipping yield helps to detemine the impact of soil nitrogen reserves. If the turf is growing too fast (desired clipping yield is usually between 10 and 60 ml/m²), additional nitrogen is not needed, even when the GP model recommends application of…
