Weight of moisture soil > weight oven drying soil,

So, water content = weight of moisture soil- weight oven drying soil.

Weight of Water = Weight of moisture soil - Weight oven drying soil.

Whereas, Water Content = Weight of Water / Weight of Solids.

Calcium carbide method is quick and accurate than oven drying method.

W = weight of water/ weight of solids.

Weight is calculated when water is present and water is absent.

Yes, calcium carbide should be the answer as it is the most accurate method.

Calcium carbide is a quick method but not most accurate than oven drying.

So, Accurate method for determination of water content is oven drying method.

Torsion balance method is also most accurate method for soils but not given in option.

Calcium Carbide is more accurate as during Oven Drying organic matter can be vaporised from the soil.

Calcium Carbide usually known as RMM( Rapid Moisture Meter test ) is a field test method.

Oven drying method is a lab method test with proper temp. control. So due to temperature control so the test result is most accurate 24 hr. 105 - 110 degree celsius.
