Measurement of Soil Moisture: 4 Methods

Measurement of Soil Moisture: 4 Methods

A soil is sampled, put into a container, weighed in the sampled (moist) condition, oven dried, and weighed again after drying. Drying is done at 105-110C (221F-230F) to constant weight (2 hrs. for small samples, but as much as days for bulky clayey soil samples and low airflow in the oven).

How does air dry soil differ from oven dry soil?

Jun 24, 2020 If the sponge is placed in an oven at 105 C, it will lose water, and therefore lose mass. Similarly, air-dried soils contain water. Air-dried sands retain the least water, while air-dried clays retain the most relative to oven drying. Subsequently, one may also ask, what is air dried soil? In soil science and biogeochemistry, the term “air ...

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).
