A site near Devon, Alberta was used to monitor salt transport over time and test the effect of irrigation. Direct push EC (PTC) was regressed against coincident chloride concentration measurements from soil cores. The PTC EC data was then converted to chloride measurements.
Using the EM-31 instrument, two site-wide surveys were taken in 2008 and 2010 and both were regressed against coincident PTC EC data converted to chloride. The EM-31 survey was converted to chloride using the regression relationship. Salt mass was determined by kriging with a locally varying mean (KLVM) and found an increase of 3 tonnes which is within our uncertainty. A 20 by 20 m test plot was surveyed using ERT in 2009 and 2010. ERT results were regressed against chloride samples. ERT was transformed by the regression relationship.
KLVM was used with chloride samples and transformed ERT and found a decrease of 32% in chloride mass.
