The second means of addressing forage mass was to use a disk meter (Bransby et al.
Quadrat forage samples and calibration samples for the disk meter were dried in a forced-air oven at 55[degrees]C for 24 h, followed by immediate weighing.
Neither the estimate of forage mass measured by quadrat nor that with the disk meter markedly differed between periods (Table 1).
Though there was a greater than anticipated difference in forage mass between quadrat and disk meter estimates, they do reflect that desired conditions were achieved.
