Composition and chemical properties of the soils of the city of Santiago de Compostela, northwestern Spain

Urban Farm DB summary

This study analyzed 56 urban soil samples (0–20 cm) from Santiago de Compostela, Spain, across various parent materials and land uses, to characterize their physicochemical properties. The soils were found to be coarse textured (sandy loam), acidic (pH 4.7–6.9), with moderate to high organic matter (13–137 g organic C kg−1). Unlike many urban soils, they did not exhibit alkalinity, high bulk density, or large amounts of artifacts, showing similarity to natural regional soils.
