Replication Data for: Dataset of Soil Properties for Soil Organic Carbon (SOC) Estimation in Andean Agroecosystems

In August 2022, 189 agricultural fields were sampled using a composite sampling approach consisting of five subsamples collected from the center of each field. Soil samples were taken at a depth of 0–24 cm for physicochemical analysis, and at 15 cm for dry bulk density (Bd) determination using the core method.

This involved extracting two samples from the center of each field (at 0.15 and 0.30 m depth) using volumetric cylinders with diameters of 50 mm and heights of 50.8 mm. The measured variables included pH (1:1 soil–water suspension), electrical conductivity (EC) (1:1 extract), available phosphorus (P) (Olsen method), available potassium (K) (buffered acetate extraction), soil organic carbon (SOC) determined using the Walkley and Black method, and cation exchange capacity (CEC) measured with buffered ammonium acetate at pH 7.0.
