SALINITY ESTIMATES IN IRRIGATED SOILS USING ELECTROMAGNETIC INDUCTION

Salinity Estimates in Irrigated Soils Using Electromagnetic Induction

Electromagnetic induction (EM) is a useful mean of assessing soil salinity in large areas, particularly after its calibration on different soils. Electromagnetic induction was used to monitor spatial and temporal changes of soil salinity within the saline irrigation district of Flumen, Spain. Soil salinity patterns in this region are entangled because of intensive land leveling and irrigation. ...

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 ...
