Interpretive Summary:

Technical Abstract: This database is a comprehensive compilation of hundreds of published accounts of the use of apparent soil electrical conductivity (ECa) at the field and landscape scales with electrical resistivity (ER) or electromagnetic induction (EMI) sensors to measure a variety of soil properties. Version 1.0 of the database lists nearly 470 studies where ECa was used to measure, map, and/or monitor several soil properties, either directly or indirectly. The directly measured soil properties are: salinity – including total dissolved solids, sodicity, inorganic C, CaCO3, and nutrients (237 studies); water content – including macropore porosity, water table depth, and irrigation canal seepage (105 studies); texture-related – including sand, clay, depth to claypans or sand layers, soil layers, topsoil thickness, depth to bedrock, saturation percentage, soil type, and map units (133 studies); bulk density related – including compaction, and rock content (18 studies); organic matter related – including soil organic carbon, total carbon, and organic chemical plumes (24 studies); cation exchange capacity (13 studies); temperature (2 studies); and mineralogy (1 study). The indirectly measured soil properties are: groundwater recharge (6 studies); heavy metals (1 study); herbicide partition coefficients (2 studies); leaching – including leaching fraction (5 studies); soil drainage and drainage classes – including hydraulic conductivity (7 studies); soil resistance to penetration (1 study).
