description
Provides globally consistent estimates of soil pH in the 0–5 cm layer, derived from the SoilGrids 2.0 database. Soil pH is a master variable governing nutrient solubility, microbial activity, and overall soil fertility, making it essential for assessing land productivity and environmental suitability for crops or vegetation.
methodology
Predictions are generated using machine-learning models trained on global soil profile observations and environmental covariates such as climate, elevation, and remote sensing indices. The model estimates pH in water (1:1 ratio) at multiple depth intervals; this indicator isolates the topsoil layer (0–5 cm) to capture the conditions most relevant to plant roots and surface processes.
