Two grass measurement systems are commonly used in the UK, sward height (cm) and kgDM/ha (cover/mass).
To measure sward surface height you can use a ruler, a sward stick (available from your levy body or seed merchant) mark cms on a welly, piece of alkathene pipe or any other tool you carry with you.
To measure kgDM/ha you can use a sward stick showing kgDM/ha or a rising plate meter.
