ABSTRACT: Soil/porous media water content is a primary factor governingmass and energy exchange at the air-soil interface.These soil surfaceprocesses globally influence hydrology and climate as well as a wide arrayof agricultural and engineering applications.Electromagnetic (EM) sensorshave been widely used for determining soil moisture content based on thestrong dependence of EM signal properties on volumetric water content.Dr. Jones'presentation will address 1) basic principles of in-situ soilmoisture content measurements; 2) categories and design differencesamong EM soil moisture sensors; 3) factors that may affect themeasurement accuracy of EM sensors in the field; 4) developmentopportunities toward novel instrumentation such as near-surface, skin, andfield-scale soil moisture sensing and 5) global needs for future sensordevelopment.
Dr. Jones is Professor of Environmental Soil Physics in the Department of Plants, Soils and Climate atUtah State University,Logan,Utah,USA. He began his work on dielectric measurements as aPostdoctoral Fellow in the Volcani Institute in Rishon LeZion, Israel from 1997-1999. His currentresearch interests include determination of soil physical properties and processes, dielectric andthermal measurements, instrumentation, and precision agriculture in reduced gravity environments,such as the International Space Station. Dr. Jones serves as an associate editor for the Vadose ZoneJournal and is a Fellow in the Soil Science Society of America.
