on the sample is 27 – 30 lbs., which closely simulates the pressure in a standard bale of hay. If

you do not have the #831 short pin prod, squeeze a handful of hay around the tip of the 830-2

for an estimate of windrow moisture levels.

SECTION C: FACTORS AFFECTING YOUR READINGS:

GRAIN TEMPERATURE

 Wide differences may exist between the grain temperature and that of the instrument.

Under such conditions, the temperature of the samples may change so that it becomes

difficult to measure it accurately.

MOISTURE DISTRIBUTION

 This condition prevails when grain is drying, especially when using heat or rapid

circulation of air. Differences in moisture content are also found in different parts of the

same field because some parts may mature at different times. Actual differences in

moisture content can also be found in a single ear of corn – moisture usually being

greater near the stalk.

SAMPLE SIZE

 The G-7 tests a small sample and therefore its reading is directly related to the moisture

content of the grain from where the sample was selected.

 If the initial two or three tests indicate uniform moisture content, there is no need to make

additional tests on other samples. On the other hand, if the initial tests indicate considerable

variations in moisture content among the various samples, we recommend that you test

more samples in order to have a more accurate determination of the average moisture

content, and the range of moisture present.

UNIFORMITY OF SAMPLE

 When checking the operation of a dryer, select samples of grain from different locations to

determine how well the drier is performing, since the drying rate may not be uniform

throughout the grain. Also, when checking the moisture content of grain in a bin, it is

necessary to select various samples from different parts of the bin and test them individually.

In such cases it is very important to ascertain that there is no grain in any part of the bin with
