11 - Using the Correct Measuring Technique
Different platemeter measuring techniques can alter
pasture covers by as much as 600 kgDM/ha. This can be the
difference between thinking there is adequate or even surplus
pasture available and all is well, or pasture deficit and urgent
action is required.
All pasture measurement techniques require calibration
to convert the actual reading to dry matter. The technique
that is used when walking around the farm taking the
measurements needs to be the same as that used to calibrate
the Platemeter. This technique is to place the plate on top of
the pasture with no downward force, and then push the shaft
to ground level – making sure the plate is vertical when the
shaft hits the ground.
Taking measurements by holding the Platemeter 10cm or
more above the top of the pasture and plunging the plate
onto the pasture will give lower, incorrect readings. This is
because the downward force of the plate compresses the
pasture more than occurred when the calibrations were down,
giving a lower average height and cover readings.
