Test C

hSelect up to five large, slower-drying stems from a section

of the windrow.

hPlace them one at a time across two adjacent points on the

# 831 short pin prod.

hThe average of these stem readings should be about two to

five points higher than the actual moisture content.

Notes

hRepeat these steps in different parts of the field and pay

special attention to the areas where the hay is heaviest.

hThe amount of variation found among windrow readings as

well as the average stem moisture should be taken into

consideration before the decision is made to start baling.

FACTORS AFFECTING YOUR

READINGS

Because of the many variables that affect the electrical meter

readings, the indicated moisture content should not be used

as an absolute quantitative measurement. Meter readings are

very useful guidelines for the safe storability of hay.

Meter readings become more significant when they are

considered in the light of the density of the bales, anticipated

handling and storage, and prevailing climate conditions.

Range of Moisture Content

The F-2000 is designed to test moisture in hay over a range

of 6%-40%. Readings over 30% should be used only as a

qualitative indication of high moisture content. Delmhorst

moisture meters use the relationship existing between electrical

conductivity and moisture content in hay. As moisture content

increases, so does the conductivity.

Tests on hay at high moisture content, over 25%, are less

accurate. This is mostly due to the variability in moisture

distribution. The reduced level of accuracy in the high range

does not significantly affect the usefulness of the meter, as a

few high readings indicate that some action be taken to dry

the hay to avoid spoilage or even self-combustion.

While it is important to note the average of several readings,

it is even more important to note the high readings and the

frequency at which they occur.
