## 1 Introduction  
Normal stresses, such as mechanical and hydraulic types that impact soil, could facilitate arrangements of its particles and, at the same time, degrade them. The observation and evaluation of such situations may influence soil management. Attempts have been made in the experiment presented in this report to evaluate, through electromagnetic pulse energy interaction using the ground penetrating radar (GPR), how the soil's naturally arranged particles are delineated when altered by anthropogenic vertical stress acting on them. The qualitative assessment was supplemented with a laboratory analysis of the physicochemical properties (porosity, bulk density, and moisture content) of samples taken at some selected points in the test area. The expected outcome of the investigation is the test of the usability of the geophysical technique (GPR) adopted in this study to identify deviations in the soil's void and solid constituent arrangement in a fast, cheap, and repeated way, fostering spatiotemporal variation characterization. The scope of this study is to use the experimental test site as a case study. Thus, the results do not represent the generalization of soil, particularly due to the complexity of the soil media. Soil grain sizes, which connote its texture and the soil structure, significantly affect water infiltration capacity and storage because these properties promote the reduction in runoff and, thus, increase the amount of water flow to the deeper part of the soil profile [1]. The fertility of the soil and the crop yield from it may be influenced by these soil attributes. Apart from the generic importance of soil, it has also been found that soil plays important roles in the ecosystem, with the capacity to store very large amounts of carbon. For instance, nearly 80 billion Tonnes of carbon have been estimated to reside in European soil [2]. Understanding soil significance may influence its management practices because the degradation of some of its properties may adversely reduce its basic role functions. Soil structure is a physical property that represents the natural arrangement of soil grains into discrete soil units known as aggregates, which may include pores and channels [3]. The aggregate can be in different forms and shapes, ranging from granular to angular to platy. The formation of the soil structure has a significant influence on the porosity of the soil. Hence, pore arrangement enhances the flow of water and air, the germination and growth of plants, and also influences the organisms' activities within the soil. Several factors lead to the degradation of soil, particularly as related to macrostructure, which constitutes a major global environmental challenge that these non-renewable resources face. Some studies describe soil alteration processes as having significant impacts on plant growth, leaf area development, biomass yields, and overall crop yields [4]. This is because the dynamic environmental inputs in plant growth, such as water, nutrients, and air, in one way or the other, have direct links with the soil porosity, which relates to the soil structure. Additionally, the physical support provided by soil to plants is huge, shielding them from excessive wind [3]. Thus, soil degradation that may negatively influence its porosity ought to be constantly evaluated to inform a control measure that can be put in place to ameliorate it. [PERSON] and [PERSON] [1] concluded in a review that agricultural activities that promote crop yield influence the formation of aggregates in soil and, thus, increase the development of soil structure. Some soil management practices, such as crop rotation, conservation tillage systems, and inoculation, have greatly influenced the soil's health status through the improvement of the soil structure. Thus, degradations via alterations may hinder the state of the soil [5]. For instance, soil structure degradation has been described as a hindrance to water infiltration, leading to surface water runoff and soil erosion [6; 7; 8].
