“…The majority of granular materials are poor conductors, however conduction within a soil matrix is principally electrolytic in view of the presence of water inside pores. It is obvious that the nature of the fluid plays an important role; when the salt concentration of water increases, the fluid becomes more conductive [21]. Since an electrical potential is applied between two electrodes, the electric charges move away from their equilibrium position inducing conduction phenomena.…”

“…Specifically, electrical resistivity has been developed in geotechnical engineering, agriculture and geology since it is considered as a quick and non invasive method [17][18][19][20]. Soil resistivity values less than 100 Ωm reveals that soil nutrients are abundant in this area; however, sites with soil resistivity greater than 600 Ωm are reported as poor in soil nutrients [21]. Other investigations show that yields of crops are damaged by salinity when the electrical conduc-tivity value (inverse of resistivity) is in the range of 2 to 8 dS/m [3,22].…”

Soil salinity is becoming one of the most devastating environmental hazards over the years. Soil investigation involves fast, low cost and non disturbing methods to measure soil characteristics for both construction projects as well as for agricultural use. The electrical resistivity of saline soils is greatly governed by salt concentration and the presence of moisture in soil matrix. Experimental results of this investigation highlight that there is a significant relationship between the electrical resistivity of soil samples mixed with chloride solutions (NaCl, KCl, and MgCl 2 ) at various concentrations, and soil physical properties. Correlations represented by quadratic functions were obtained between electrical resistivity and soil characteristics, namely, water content, degree of saturation and salt concentration. This research reveals that the obtained correlations between electrical resistivity, salt concentration, water content and degree of saturation are effective for predicting the characteristics of salt affected soils in practice, which constitute a governing element in the assessment of saline lands sustaining infrastructure.

“…Tso et al [18] demonstrated the inaccuracy of converting geoelectric sections obtained from the application of the Electrical Resistivity Tomography (ERT) method to moisture images, without considering other factors such as changes in texture and/or pore water salinity. Ozegin et al [19] presented successful results on the application of the ERT method in the determination of chemical properties of agricultural soils. Correlation analyses between the results of chemical analyses performed on soil samples and geoelectric models were required for the estimation of soil chemical properties.…”

Seeds require adequate soil moisture prior to planting, and pre-sowing irrigation depth (PSID) represents the optimum seed moisture level. This work proposes a new methodology to obtain soil physical properties and PSID, that includes the application of the electromagnetic profiling method (EMP) as a fast and non-invasive technique. Soil electrical resistivity measurements obtained from an EMP survey are combined with soil moisture and salinity information as experimental input for the PetroWin program. The PetroWin program uses Ryjov’s theoretical model to determine fines content and porosity, and then, PSID values are determined. At the study site, variations in soil resistivity were controlled by variations in fines content and soil moisture, and not by variations in soil salinity. The rooting depth of the crops was limited by a soil thickness of 0.6 m. A PSID between 8 and 9 cm was determined for the site, resulting in a total water volume required of 5313 m3 to ensure that soil moisture reaches the field capacity. The proposed methodology constitutes an effective and efficient tool for the determination of the physical properties and irrigation parameters of agricultural soils and, consequently, for the sustainable use of irrigation water.

“…Most importantly, the first step to achieve optimization of agricultural output is to identify fertile soil that can give high yield crops. Geophysical methods have been found to be relevant in agricultural practice and their applications have been demonstrated in the literatures [2][3][4][5].…”

Accurate knowledge of soil fertility is required to promote global food security for life sustenance. Literatures have shown that electrical resistivity method is effective for agricultural site selection without passing through the rigor of soil test. However, the factor responsible for inconsistence in resistivity signature with soil fertility from one place to another, effect of soil texture and depth variation on crop yield are the questions this work geared at providing answers. Ten Vertical Electrical Sounding (VES) were conducted across the study area using Schlumberger array. Res1Dinvers was used for the inversion model, using Least Square method. Twenty soil samples were obtained in the VES points, two samples per point. One sample each at first and second layer. Result of the apparent resistivity showed that areas with high-excellent crop yield have resistivity signature above 500 Ωm while areas with low yield are characterized by values less than 500 Ωm. In both areas of low and high-excellent crop yield, the result of geochemical analysis indicated that Nitrogen, phosphate, and Potassium varied as 59-61%, 43-54mg/kg and 49-51mg/kg, respectively except for organic matter content that was above 3.8% in the first layer have high-excellent yield while low yield soil showed less than 3.8% in their first layer and even if the second layer’s organic matter is above 3.8%. This study has shown that organic matter has significant effect on soil resistivity signature than others soil nutrients (Phosphate, Potassium and Nitrogen). The study shows that soil’s first layer (0-0.3m) is the most suitable depth conducive for soil minerals occurrence for optimum agricultural output.
