Determination of Soil Properties from Electrical Measurements in Agricultural Plots, Villa de Arriaga, San Luis Potosí, Mexico

The knowledge of agricultural soil properties is crucial for the auspicious selection crop, irrigation and fertilization types. This study contains results field laboratory application electrical measurements used to obtain fines content, porosity, hydraulic conductivity cation exchange capacity (CEC) in three plots purpose growing barley. values content were attained using samples Ryjov's algorithm, which comparable calculated from textural analyses Bouyoucos. In plot A, an Electrical Resistivity Tomography (ERT) profile, along with moisture salinity, show high-resolution outcomes determine properties, these are related a clear image thickness, as well identification horizons. Profiling (EP) survey conducted showed higher productivity than ERT method, resulting maps. display A-lowest, B-moderate C-higher range CEC values. result conforms crop yields per hectare fertility analysis carried out on each land plot, confirms not only effectiveness EP method but also their properties.
