SPATIAL PREDICTION OF SOIL SALINITY USING ELECTROMAGNETIC INDUCTION TECHNIQUES

Monitoring for Temporal Changes in Soil Salinity using Electromagnetic Induction Techniques

struments have received the most attention for fieldscale agricultural applications, particularly the EM-38. Electromagnetic induction surveys are often used in practice to In 1992, Dı́az and Herrero discussed the monitoring estimate field-scale soil salinity patterns, and to infer changing salinity of soil salinity conditions with time in two fields using conditions with time. We developed a st...

Quantitative Evaluation and Uncertainty Assessment on Geostatistical Simulation of Soil Salinity Using Electromagnetic Induction Technique

Diagnosis of soil salinity and characterizing its spatial variability both vertically and horizontally are needed to establish control measures in irrigated agriculture. In this regard, it is essential that salinity development in varying soil depths be known temporally and spatially. Apparent soil electrical conductivity, measured by electromagnetic induction instruments, has been widely used ...

Statistical Modeling and Prediction Methodologies for Large Scale Spatial Soil Salinity Characterization: A case study using calibrated electromagnetic measurements

Soil Water Content Monitoring Using Electromagnetic Induction

The use of electromagnetic ~EM! induction measurements was evaluated to predict water content in the upper 1.50 m of a prototype engineered barrier soil profile designed for waste containment. Water content was monitored with a neutron probe, and bulk soil electrical conductivity was monitored with a Geonics EM38 ground conductivity meter at ten locations at approximately monthly intervals over...
