3.1 Quality of the hay and Test Readings
Because of the many different conditions which affect test
readings, the indicated moisture content should not be used as
an absolute, quantitative measurement.
Test readings are, however, very useful guidelines for baling
and storing hay. Understanding these conditions can help to
obtain accurate test readings.
• Bale Density: The tighter/denser the bale, the higher t
he moisture readings. Compaction also varies within
each bale.
• Natural variations within the plant during drying: The
higher the moisture content, the wider the
variations. Consistency of results improve with drier
crop.
• Sweating: Higher readings may occur during the first
couple of days after baling, moisture readings
may be low and then climb during the "sweating"
process. As the hay dries, moisture readings should
drop and continue to decline as the hay becomes
progressively drier. It is important to continue to
monitor moisture for several days.
• Some preservatives increase conductivity initially:
Until the preservative is absorbed, usually in 1-2 days,
it may cause the moisture reading to be 2-4% above the
same hay which is untreated.
• Tester has been calibrated on 100% alfalfa hay. Other
herbs give different readings.
Test readings are, however, very useful guidelines for baling and
storing hay.
3.2 Rectangular or Square Bales:
Because the inside of each bale is not uniform in density its
leaf- to -stem ratio, moisture readings will vary from one part
of the bale to another. It will read highest if the probe is
inserted into the "dense" side. Tester will give higher readings
in tight bales than in loose bales.
