摘要

Indirect measurement of soil conductivity in agricultural soils is well established but has yet to be established in tidal marshes. Tidal Marsh combines three soil properties that affect conductivity: clay; water content; salinity. The EM38 instrument was previously used to map salinity of the tidal marsh and found areas with conductivity higher then salinity values, measured with a refractometer, produce. A model and laboratory experiments were designed to find the reason behind the high conductivity values. Data showed presences of conductive clay minerals in the sediment. Also an iron sulfate was found in the sediment and could also lead to increased conductivity. Further studies and laboratory experiments need to be conducted to better calibrate model of tidal marsh.
