An adiabatic boundary condition with cylindrical perfect conductors for improved approximations from heat-pulse measurement near the soil-atmosphere interface Geoderma (IF 5.6) Pub Date : 2024-07-14 Wei Peng, Yili Lu, Tusheng Ren, Robert Horton
The cylindrical-perfect-conductors (CPC) theory, which assumes an infinite and homogeneous soil medium, can be used to analyze heat pulse (HP) measurements to estimate soil thermal property values. However, when a HP sensor is positioned near the soil surface, the CPC theory is not valid because of the change in media properties at the soil-atmosphere interface. In this study, a CPC solution considering

Estimating the universal scaling of gas diffusion in coarse-textured soils Geoderma (IF 5.6) Pub Date : 2024-05-09 J. Valdes-Abellan, D. Benavente, B. Ghanbarian, P. Moldrup, E. Arthur, T. Norgaard, L. Wollesen de Jonge
Gas diffusion, , in partially saturated soils, constitutes a critical topic in soil sciences. However, it is a complex process and this limits its characterization and estimation. In this study, we analyzed and parameterized the soil gas diffusion using a combination of percolation theory (PT) and the effective-medium approximation (EMA). Here, we selected 126 coarse-textured soils with measurements

High-resolution soil erosion mapping in croplands via Sentinel-2 bare soil imaging and a two-step classification approach Geoderma (IF 5.6) Pub Date : 2024-05-07 Lulu Qi, Yue Zhou, Kristof Van Oost, Jiamin Ma, Bas van Wesemael, Pu Shi
Erosion-induced lateral soil redistribution leads to spatially heterogenous soil composition, which can be captured through the distinctive spectral reflectance of soils under varying levels of erosion influence. This points to the potential of using remotely sensed soil spectra to detect severe erosion and deposition hotspots in exposed croplands and, importantly, further differentiate the intra-class
