WebApr 11, 2024 · To characterize the DRS of different soil matrices, we collected four types of soil samples from both modern and ancient soils. The modern soil samples were collected from the mixing of multiple tropical saprolite profiles in Hainan Island, China (HN-SP, 19.25–20.01°N, 109.65–110.60°E, Table S1 in Supporting Information S1).

WebFor SOC and pH, the best overall results were without preprocessing the soil spectra. Moreover, the cubist model was the most accurate in predicting soil properties. Finally, our study showed evidence of the potential and feasibility of using this soil spectral library to estimate soil properties such as pH(H 2 O), sand, clay, and SOC.
