The sealing thickness property refers to the depth of the compacted or sealed layer within the soil, which is typically a result of intense rainfall, drying, or tillage practices. This layer, which forms in fine-textured soils, can significantly reduce water infiltration and root growth, leading to reduced soil aeration and potential surface runoff. The sealing thickness property is crucial for understanding soil erosion risks and water management in agricultural systems. Source: Pagliai, M., & Vignozzi, N. (2002).
