Fig. 2. (a) Soil conductivity meter response showing normalized sensitivity for Geonics EM-38 and Dualem-2. This figure also indicates depths of thermocouple soil temperature probe locations in relation to normalized sensitivity of the EM-38. (b) Soil conductivity meter normalized cumulative response for both Geonics EM-38 and Dualem-2 (http://www.dualem.com/gsem.htm, verified 23 Mar. 2006). This figure also indicates normalized cumulative response relative to the soil core depth of 0.3 m used for this study; cumulative response at 0.3 m was >50% for the EM-38 and nearly 30% for Dualem-2.
