1/ If the sample weight is too small or too dry for a moisture test, follow the procedures on the back of this form to complete the moisture test.

FORM C-2: SOYBEAN
If the sample weight is too small for moisture test, sufficient grains of known moisture content (use same class and stage of maturity) will be added to the sample so that a moisture test can be made. The moisture content of the sample can then be derived using the following formula:
	E =	( A + B ) D - ( B x C)
		A
Where	A = Weight of small or dry soybean sample . . . . . . . . . . . . . . . . . . . . . . .				. ___	Grams
