Abstract

fetched live from OpenAlex

This study used a large dataset of mineral topsoil samples collected from agricultural fields across Ontario through the Ontario Topsoil Sampling Project (OTSP). Previously, the OTSP dataset was used to assess the soil health scoring functions (Chahal et al., 2023) and SOC:clay ratio as an indicator of soil functionality (Chahal et al., 2024). The goal of the present study was to evaluate the impact of agricultural management and environmental variables on soil C indicators (SOC, 96-h C mineralization potential (Cmin-96h), POXC, Solvita CO2-burst, and ACE) and indicators of thermal stability of soil C using programmed pyrolysis (HI, OI, and T50). We also assessed the associations among these soil C indicators at the landscape scale to comprehensively assess the major drivers of soil C.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
