Site productivity is often regulated by soil depth, which is essential for calculating nutrient quantities and soil water-holding capacity. To accurately estimate soil volume, information on the proportion of coarse fragments is also required. Traditional soil-sampling methods, are destructive, time-consuming, expensive, and provide only point data. Due to soil heterogeneity, such data are accurate only at the sampling point and cannot be considered representative of the entire site. Ground-penetrating radar (GPR) is an on-site, non-destructive, easily replicable measurement technique. It enables the identification of zones with different production characteristics across large areas. The principle of the GPR method is based on the penetration of electromagnetic waves, which are transmitted into the soil in pulses by the transmitting antenna. When the electromagnetic waves encounter a boundary between different materials, part of the wave is reflected and detected at the surface by the receiving antenna. The literature contains several studies that have successfully determined the depth of (skeletal) soils, identified boundaries between soil horizons, and predicted the proportion of coarse material and clay. Nevertheless, compared with the use of GPR for determining other properties, there is still considerable room for further development in this area.
