Abstract:
The soil biogeochemical data contains a four-year time series (2019–2022) of soil biogeochemical measurements collected at the Bocamina post-industrial revegetation trial in south-central Chile (39° S, 73° W). Researchers monitored five cover-treatment regimes (coconut fiber geoblanket, hydroseeding, direct sowing, no-cover, and bare-soil control) to assess their effects on soil recovery. The dataset supports analyses of soil structural resilience, organic matter accrual, and nutrient dynamics under contrasting restoration strategies. Sampling protocols adhered to standard soil-science procedures. No outlier filtration was applied—extreme values were retained to maintain full transparency of field variability. The experiment employs a randomized block design. Each year's campaign ("First Year" through "Fourth Year") sampled all treatments across six replicated plots per block. Spatial metadata (latitude/longitude) enables integration with geospatial analyses, while consistent plot identifiers facilitate temporal tracking of treatment trajectories.
