Sward Composition
Method
Measure percentage grass, weeds, pests & diseases as a factor of 100 over an area of 1 square metre.
Timing
During and out of season
Effects of incorrect procedure
- Poor surface durability.
- Poor surface playability.
Equipment
- Quadrat
- PQS Tables
Practical Tips
Use lightweight timber frame (like a picture frame) ‘strung’ with string, wool, hemp, jute, polypropylene, nylon line or fishing line. Strung to form a 10 x 10 grid to represent 100 (%)
Surface Levels
Method
Measure the variation of the localized surface levels over the length of a 3 m straight edge
Timing
During and out of season
Effects of incorrect procedure
- Poor surface playability
- Risk to players/officials
Equipment
- Straight edge, wedge & spirit level.
- PQS Tables
Practical Tips
Substitute test equipment can be made of other materials particularly wood, i.e. goal uprights or crossbars, and metal. However, keep in mind that wood can warp and metals can be heavy and prone to rust (oxidation) so appropriate treatment and care should be exercised. The Straight Edge & Wedge can also be used, with a spirit level, to check gradients.
Sward Height
Method
Measure the average height of grass across the pitch
Timing
During and out of season
Effects of incorrect procedure
- Poor surface durability.
- Poor surface playability.
Equipment
- Rising plate or alternative measuring device.
- PQS Tables
Practical Tips
- Something as simple as a pencil or a wooden, plastic or metal rule can do the same thing as could a tyre depth gauge.
- Measure random areas across the pitch, not just the high wear areas
Pitch Dimensions
Method
Check different dimensions to see if they conform to RFL regulations
Timing
During season
Effects of incorrect procedure
- Delay to start of match to allow remedial action.
- Match postponed by officials.
- Reported to league
Equipment
- 100 m surveyors measuring tape
- Ground pin
Practical Tips
- This is easier with two people to complete and should take approx. 30 mins to complete.
- Regularly check markings that are easily worn; ie the penalty spot.
