A procedure is described for estimating salinity of water samples in the field using a geophysical earth resistivity meter and four‐electrode conductivity cell. Using field collected water samples, a linear relationship of Y = 1.02( X ) + 0.12, r = 0.996, was obtained between EC 25 values determined using a commercial laboratory bridge and cell ( Y ), and those determined using an earth resistivity meter and an easily fabricated, four‐electrode conductivity cell ( X ).
