Correct soil weight from air-dry to oven-dry

Correct soil weight from air-dry to oven-dry

The second weight is the oven-dry soil (ODsoil) weight of the sample and the difference between the ADsoil wt. and ODsoil wt. is the weight of water in the ADsoil sample. The moisture content is expressed as a ratio of the air-dry to the oven-dry weight (ADsoil ODsoil), but the correction factor is less than one so (ODsoil ADsoil).
