Moisture Content of Soil
As mentioned above the degree of moisture pertains to relative concentration (rather than the absolute amount) of water, independent of the size of sample. In order to find out the moisture content of soil, a sample of moist soil, usually taken from core o f field is weighed. It is then dried in oven at a temperature of 100 - 110ºC, and weighed again. The water lost by the soil represents the soil moisture content in the moist sample. The most common means of expressing soil moisture content is the mass or volume of water associated with a given mass or volume of soil solids.
