Answer:
Explanation:
1. Gravimetric Method: This method is the classical procedure used as the check for all other methods. A soil is sampled, put into a container, weighed in the sampled (moist) condition, oven dried, and weighed again after drying.
2. Electrical Conductivity Method: This method is based upon the changes in electrical conductivity with the variation in soil moisture.
3. Measurement by using Tensiometers: Tensiometers measure the matric potential of soil moisture in situ (field) with the use of a porous clay cup attached to a tube filled with water.
4. Neutron Scattering Method
