Measuring in situ soil water content is an important part of many field research projects. Like many technology areas, instruments that measure soil water content are evolving quickly with new techniques coming into the market regularly. To make an informed decision on what technology is best for in any given situation, it is important to understand the options available on the market. The objective of this seminar is to give an overview of the different methods to measure soil water content, discuss the theory behind the measurement, and provide some examples of field research and what technology might apply in each situation. The main measurement techniques that will be discussed are gravimetric sampling, dielectric methods including TDR and FDR/capacitance, neutron probe, and dual needle heat pulse. Participants in the seminar should gain an understanding of the fundamentals behind each of the methods and in what situation each may apply.
