For Mechanical Plate Meters

Height readings can be converted to field cover using a simple formula or a ready reckoner based on the density of typical well-managed leafy swards. 

The electronic plate meter does the calculations shown in the example below automatically. After taking fifty readings all you have to do is press the cover button and the display reveals the average cover of the area you have just recorded.

Rising Plate Meter Conversion Formula 

Rising plate meter assessments can be calibrated to accurately reflect individual sward characteristics by measuring the DM yield of representative samples. Following assessment, fields should be ranked in order of cover (from highest to lowest) to determine the order in which they should be grazed. The field cover or height should also be used to determine when grazing can commence and when cows should be removed from the field.
