Aim:
Have a number of uses in measuring and maintaining turf height.
To accurately measure grass height.
To monitor consistency of height of cut across the surface.
Used to support surface standards within the PQS system.
Method:
A grass height gauge is placed vertically onto the turf surface, ensuring it is seated firmly and upright.
The measuring probe or plate is gently lowered until it touches the grass leaf tips, and the height is read directly from the scale.
Within the PQS system, grass height measurements are taken from multiple locations across the surface to assess uniformity and compliance with required standards.
Timing:
Grass height should be measured regularly during the growing season.
PQS assessments can be carried out at any time of year when grass is actively maintained.
Grass height should be checked after mowing adjustments or changes in maintenance regimes.
Effects of Incorrect Procedure:
Incorrect positioning of the gauge can lead to inaccurate readings.
Failing to take multiple measurements may give a misleading impression of surface consistency.
Inaccurate grass height control can negatively affect turf performance, playability, and presentation.
Equipment Selection:
A calibrated grass height gauge with clear metric markings is standard.
Digital or manual gauges may be used depending on preference and accuracy requirements.
The gauge should be robust and suitable for fine turf measurement.
Practical Tips:
Ensure the gauge is clean and free from debris before use.
Take measurements from representative areas, avoiding worn or damaged spots unless specifically assessing them.
Record results consistently to track changes and support maintenance decisions.
