Abstract
During the soil survey of Gibson County, Tennessee laboratory data from some characterization samples indicated that the Routon silt loam (fine-silty, mixed, thermic Typic Ochraqualf) should be classified as a Natraqualf. Because field mapping was completed, a series of transects were conducted using an aboveground electromagnetic conductivity meter to separate saline from nonsaline soils. The meter was calibrated using average electrical conductivities weighted to 3.28 ft (1-m) depth. Transects were completed in 12 Routon mapping units. Results show that only one of the mapping units may need to be reclassified based on calibrated meter readings that were correlated with Na− adsorption ratios. The aboveground conductivity meter proved useful for this application on loess-derived soils in west Tennessee.
