Understanding
Hay Conditions
and Test Readings
Many variables affect the accuracy of
test readings. Understanding these
variables can help to obtain accurate
test readings.
IMPORTANT:
Because of
ables which affect test readings, the
indicated moisture content should
not be used as an absolute, quantita-
tive measurement. Test readings are,
however, very useful guidelines for
baling and storing hay.
• Bale Density: The tighter the bale, the higher the moisture readings. Com-
paction also varies within each bale. Although each brand of baler feeds hay
into its chamber differently, in general, small, rectangular bales are denser
toward the bottom or "tight" side; and large rectangular bales are densest in
their upper corners.
• Natural variations within the plant before proper curing: The higher the
moisture content, the wider the variations. Greater uniformity can be expect-
ed as more curing takes place.
• 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 cures, 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.
• Percent of grass in the hay: Tester has been calibrated on 100% alfalfa
hay. The more grass in the hay, the higher the moisture readings vs. actual.
Independent tests have shown that differences of up to 5 points at 20%
moisture can exist with 100% mixed grass hay.
