Precision agriculture dates back to the middle of the 1980's. Remote sensing applications in
precision agriculture began with sensors for soil organic matter, and have quickly diversified …

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 …

Apparent electrical conductivity (ECa) of the soil profile can be used as an indirect indicator
of a number of soil physical and chemical properties. Commercially available ECa sensors …

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 …

Soil apparent electrical conductivity (ECa) has been used as a surrogate measure for such
soil properties as salinity, moisture content, topsoil depth (TD), and clay content …

The measurement of soil moisture in agriculture is currently dominated by a small number of
sensors, the use of which is greatly limited by their small sampling volume, high cost, need …

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 …
