Different methods of management zone (MZ) delineation have been established over the
past 2 decades based on approaches, which have been largely constrained by the available …

Electromagnetic induction (EMI) has been used to characterize the spatial variability of soil
properties since the late 1970s. Initially used to assess soil salinity, the use of EMI in soil …

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 …

Spatial characterization of the variability of soil physico-chemical properties is a fundamental
element of (i) soil quality assessment,(ii) modeling non-point source pollutants in soil, and …

Map** 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 …

Since both the spatial and vertical heterogeneities in soil properties have an impact on crop
growth and yield, accurate characterization of soil properties at high sampling resolution is a …

Electromagnetic soundings are made to determine variations in the electrical conductivity of
the earth with depth. Electromagnetic (EM) sounding methods include natural-field methods …

Fast and accurate assessment of within-field variation is essential for detecting field-wide
heterogeneity and contributing to improvements in the management of agricultural lands …

Publisher Summary This chapter reviews the various electrical conductivity methods for
measuring soil salinity together with compatible ways for map** it, including establishing …

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