Multi-depth electrical resistivity survey for mapping soil units within two 3ha plots

Mapping Depth to Argillic Soil Horizons Using Apparent Electrical Conductivity

Maps of apparent electrical conductivity (ECa) of the soil profile are widely used in precision agriculture. A number of ECa sensors are commercially available, each with a unique response function (i.e., the relative contribution of soil at each depth to the integrated ECa reading). Our past research estimated depth to an argillic horizon (i.e., topsoil depth, TD) on claypan soils by fitting e...

Laboratory Electrical Resistivity Studies on Cement Stabilized Soil

Electrical resistivity measurement of freshly prepared uncured and cured soil-cement materials is done and the correlations between the factors controlling the performance of soil-cement and electrical resistivity are discussed in this paper. Conventional quality control of soil-cement quite often involves wastage of a lot of material, if it does not meet the strength criteria. In this study, i...

DIVISION S-1—SOIL PHYSICS Electrical Resistivity Imaging for Detecting Soil Cracking at the Centimetric Scale

soil water content. Mackie-Dawson et al. (1989) studied the evolution of the cracking system in the first 10 cm Electrical resistivity measurements at high resolution (1.5-cm elecof soil by using vertical image analysis. They observed trode spacing) were performed to detect, from the soil surface, small cracks developing within the soil. We recorded a vertical electrical significant soil struct...

Electrical Resistivity Measurement of the Molten Cordierite Glass Using Two-wire method

Electrical resistivity (ER) is a main parameter in the melting processes of glasses. However, its measurement is difficult at high temperatures. In this study the electrical resistivity of different cordierite glass samples in the molten state was measured in the temperature range of 1100˚C to 1550 ˚C using the two-wire method. It was attempted to decrease the electrical resistivity of the glas...
