Soil mapping provides detailed information on soil variability across a field, helping optimize crop nutrition, improve yields, and ensure long-term soil health. To achieve accurate soil mapping, it is essential to measure the basic properties of the soil using the appropriate sensors. Electrical conductivity (EC) is a fundamental property of materials that characterizes their ability to conduct or resist electricity. In agriculture, soil EC is the most widely used parameter for management zone delineation because it shows high temporal stability, as it is related to several soil physical and chemical properties. EC data can be translated into valuable agronomic insights with relatively high accuracy. increasing in soils with higher salt concentration. At the same time, salt concentration depends on water content and, therefore, on soil moisture. Once an EC sensor has scanned the entire field, georeferenced data is collected in the form of points to create a map that demonstrates the spatial variability of the measured parameter. Measured soil properties can provide insights into crop vigor, which can be used to adjust fertilization inputs.
