Soil Water Content Measurement Methods

This lecture covers the measurement of soil water content using direct methods like the gravimetric method and indirect methods such as nuclear methods. It explains the use of neutron probes and dielectric methods, the drying process in an oven, reworked and non-reworked samples, and the limitations of the neutron probe. The lecture also discusses the Time Domain Reflectometry (TDR) method, its principle, calibration requirements, and its advantages over the neutron probe. It concludes with the importance of water content measurements for irrigation management and geotechnical applications.
