FACTORS AFFECTING READINGS
Due to the many variables that affect the electrical meter readings, the
indicated moisture constant should not be used as an absolute quantitative
measurement. Meter readings are very useful guidelines for safe storability
of hay.
Meter readings become more significant when they are considered in
regard to the density of the bales, anticipated handling of storage, and
prevailing climate conditions.
CURING
Before proper curing has taken place, wide variations in moisture content
should be expected in both recently-baled hay and hay in the windrow.
These variations will be exposed by meter readings taken on different parts
of the windrow or bale. The higher the moisture range, the wider the
variations will be. The more curing that has been allowed to take place, the
greater uniformity in moisture distribution can be expected.
The validity of the meter readings is closely related to the care spent in
sampling the hay to be tested. Whether hay in the windrow or baled hay is
tested, the number of tests made should be increased whenever the initial
readings show considerable variations.
DENSITY
The calibration of the moisture meters applies to bales of normal "average"
density. Generally:
•
Denser bales may yield readings 1-2% points higher.
•
Looser bales tend to yield 1-2% points lower.
•
Tests in stacks usually yield readings 2-3% lower.
•
Tests on grass hay may yield readings about 3% lower.
When testing baled hay, drive the prod across the slices of the bale, not
between them. This will ensure firmer and more uniform contact.
When using the short pin prod, uniformity of pressure from one sample to
the other is achieved by applying pressure to the "pressure button" at the
end of the 467912040 handle as described in TESTING IN THE
WINDROW.
