Supplementary materials for the article "Fuzzy membership along a stable soil physicochemical gradient is associated with arylsulfatase and β-glucosidase activities"

This dataset and code package supports an observational study of 2,209 soil samples from commercial agricultural fields in southern Brazil. It includes 15 physicochemical soil attributes, arylsulfatase and beta-glucosidase activities, deidentified grouping variables, Python analysis code, selected numerical outputs, and publication figures. Principal component analysis and fuzzy c-means were used to identify continuous multivariate soil profiles. Mixed-effects models assessed associations between continuous profile membership and enzyme activities. The data do not support causal or predictive interpretations. Direct identifiers, source-row traceability, exact collection dates, row-level municipality names, and historical within-property environment classifications are not distributed.
