The video tutorial discusses the arrangement of sand, silt, and clay particles in soil, known as soil structure. It covers six types of soil structures: granular, plat, subangular blocky, angular blocky, prismatic, and columnar. Each type is explained in terms of its formation, characteristics, and impact on soil properties like drainage. The video also describes the presence of these structures in different soil horizons, concluding with a look at a soil profile.
