What does this research mean for the field?

Soil physical organization is a biologically mediated hierarchy rather than a passive geological byproduct, and integrating multi-kingdom microbiome data with abiotic variables via machine learning can accurately predict key soil functions like carbon stock and macroporosity. Novelty: ClaimNovelty.NOVEL_FINDING. Consensus alignment: ConsensusAlignment.CHALLENGES_CONSENSUS.

What question did this study set out to answer?

To evaluate whether integrating multi-kingdom microbiome profiles with texture and climate data enhances the prediction and mechanistic understanding of soil organic carbon and physical structure.

Overview

Machine learning analysis demonstrates multi-kingdom microbiomes predict soil carbon and physical structure in agricultural soils, indicating a biologically mediated structural hierarchy.

Key Points

To evaluate whether integrating multi-kingdom microbiome profiles with texture and climate data enhances the prediction and mechanistic understanding of soil organic carbon and physical structure.
Analyzed 2,251 agricultural soil samples from Quebec, Canada, profiling prokaryotes, fungi, and microeukaryotes alongside climatic and soil texture variables.
Benchmarked four machine learning algorithms (HGBR, RFR, XGBoost, and SVR) across four taxonomic and compositional data aggregation strategies.
Applied Shapley Additive Explanations (SHAP) to interpret how biological features and abiotic constraints drive soil organic carbon stock, mean weight diameter, and macroporosity.
Integrating multi-kingdom microbiome data with texture and climate yielded high peak predictive accuracy across soil structural metrics (R² range: 0.70–0.82).
High-resolution compositional representations (ASV-level centered log-ratio) outperformed family-level aggregations, indicating that soil-structuring microbial traits are strain-specific and phylogenetically shallow.
SHAP interpretability revealed that prokaryotes and fungi actively drive biochemical stabilization and physical scaffolding, whereas macroporosity is fundamentally bounded by texture, with taxa acting as bioindicators of aeration.
