Average maize yields have increased steadily over the years in the USA and yet the
variations in harvestable yield have also markedly increased. Much of the increase in yield …

Agriculture faces the challenge of feeding a growing population with limited or depleting
fresh water resources. Advances in irrigation systems and technologies allow site-specific …

It is of critical importance to understand the relationships between crop yield, soil properties
and topographic characteristics for agricultural management. This study's objective was to …

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 …

Significant yield losses in maize (Zea mays L.) from drought are expected to increase with
global climate change as temperatures rise and rainfall distribution changes in key …

Producers using site‐specific crop management (SSCM) have a need for strategies to
delineate areas within fields to which management can be tailored. These areas are often …

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 …

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 …
