SAMPLE SIZE
When testing baled hay, it is essential to take readings at several different
points in the bale. Hay moisture may vary a great deal in the same bale. For
example, at one point bale moisture may be 20% and at another over 35%.
Additional tests must be made whenever the variations among readings are
great. If there is a possibility of high moisture areas, samples from these
locations should be taken. Areas of high moisture content will spoil,
resulting in loss.
IMPORTANT: It is extremely important to note the high readings and
the frequency at which they occur.
USE OF PRESERVATIVES
Hay preservatives or stabilizers may also have an affect on meter readings.
Normally a bale of hay treated with preservatives will read higher than a
bale of the same hay that has not been treated. The readings typically
increase by 2-4% points, and 24-48 hours after treatment, the readings
between the bales tend to equalize.
Occasional higher readings may occur if, in addition to the effect of the
increased conductivity due to the stabilizer, the bales tested also show an
increase in temperature and "sweating". As the stabilizer becomes more
thoroughly absorbed and the sweating subsides, the meter readings recede
to the initial level and will continue to decrease, assuming that the bale
becomes progressively dryer.
