Feb 26, 2019 The dried sample weight was determined by subtracting an estimate of the bag tare weight, determined as the average weight of 10 empty bags that were treated the same as bags containing soil samples. Also, individual sample bags were stored in larger grocery bags while in the oven to reduce handling time and maintain order.

Place samples in oven at 60 degrees F for at least 24 hours or until cracks appear in sediment. Check oven door to make sure it latches. Place samples in desiccator when removed from oven to cool and to avoid getting moisture from the air in your samples. Weigh samples on a balance to get the dry weight.

Correct soil weight from air-dry to oven-dry

Correct soil weight from air-dry to oven-dry

Soil properties generally are expressed on an oven-dry soil (ODsoil) weight basis. The calculation of the air-dry to oven-dry, or AD2OD, ratio is used to adjust all sample weights to an oven-dry basis. To calculate the sample weight that is equivalent to the oven-dry soil weight the AD2OD ratio is applied.
