Abstract

fetched live from OpenAlex

Intensification of cropping systems improves crop productivity and soil organic carbon (SOC) storage by maintaining or enhancing existing SOC stocks. We compiled published data on SOC changes in agricultural soils globally from experiments evaluating the impact of bare-fallow reduction to determine the change in SOC storage that results from management change. Soil organic C storage under continuous and fallow-containing systems for each site was statistically compared. For the net change in SOC on a per area or on a per area and year basis, statistical differences among soil types, texture classes, climatic factors [mean annual precipitation (P), potential evapotranspiration (PET), and ratio of P/PET], and duration of the management change were determined.

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.
