Changes in Soil Properties Across a Chronosequence of Reclamation of Alluvial Gold-mine Waste in Colombia

This dataset presents the result of soil physicochemical characterization and results of field measurements performed in the alluvial gold-mine spoils under reclamation with agroforestry systems in the municipality of El Bagre, Antioquia. The area is under the influence of the company Mineros S.A. who supported the collection and analysis of soil properties.

Purpose: The objective of this research is to assess the changes in soil physicochemical and hydraulic properties across a chronosequence of restoration of sand and gravel deposits created by suction and bucket dredges after alluvial gold exploitation. The authors aim to provide a broader understanding of processes that take place in the reclaimed deposits, to provide insights on management for transition of nutrient poor and acidic deposition sites towards productive agroforestry-based systems.
