Abstract
The effect of soil salinity and soil-water content on the apparent soi l electrical conductivity as measured with the EM-38 electromagnetic c onductivity meter has been investigated. Results showed substantial ch anges in the meter's readings as soil-water content changed. The highe r the soil salinity, the more sensitive the meter's readings were to c hanges in soil-water content. A linear relationship existed between so il-water content and apparent electrical conductivity for each level o f soil salinity over the range of measured soil-water contents.
