Non-destructive measurement of soil water content and electrical conductivity has been
desired for many years. Recent development of time domain reflectometry (TDR) enables us …

Time domain reflectometry (TDR) is the most widely used non-destructive method to
determine the water content of soils and other porous media. TDR equipment can be …

The field-scale application of apparent soil electrical conductivity (ECa) to agriculture has its
origin in the measurement of soil salinity, which is an arid-zone problem associated with …

Due in large measure to the prodigious research efforts of Rhoades and his colleagues at
the George E. Brown, Jr., Salinity Laboratory over the past two decades, soil electrical …

Time domain reflectometry (TDR) is a highly accurate and automatable method for
determination of porous media water content and electrical conductivity. Water content is …

Mapping and monitoring soil spatial variability is particularly problematic for temporally and
spatially dynamic properties such as soil salinity. The tools necessary to address this classic …

The measurement of soil salinity is a quantification of the total salts present in the liquid
portion of the soil. Soil salinity is important in agriculture because salinity reduces crop …

Precision farming, site infrastructure assessment, hydrologic monitoring, and environmental
investigations-these are just a few current and potential uses of near-surface geophysical …

Recognized and advocated as a powerful tool, the role of remote sensing in identifying,
mapping, and monitoring soil salinity and salinization will continue to expand. Remote …

Electrical resistivity tomography (ERT) has proved to be a valuable tool for imaging solute
transport processes in the subsurface. However, a quantitative interpretation of …
