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 ...
متن کاملMonitoring 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...
متن کاملThe Effect of Soil Salinity and Sodicity on Soil Erodibility, Sediment Transport and Downstream Water Quality
There is an abundance of literature on many aspects of soil salinity and sodicity, and the impact of increased salt and sodium on properties, behaviour, management and productivity of soils. However the impact of sodicity on erosion and soil erodibility and sediment transport has received less attention. The aim of this study was to investigate the effects of changing soil salinity and sodicity...
متن کاملSalinity 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. ...
متن کاملSoil 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...
