Production of annual crops on the Canadian prairies: Trends during 1976–1998
Bibliographic record
Abstract
Statistics on annual crop production for the Canadian prairies, Canada’s largest agricultural region, were summarized by crop, soil zone, and province for the period 1976-1998. A brief discussion, demonstrating how these data can be used by agronomists and policy analysts to derive other information of interest to society (e.g., how much raw material is available for ethanol or strawboard production, or for C storage in soils), was presented. The results show that land seeded to cereals has remained fairly constant, but there has been a sharp decrease in the summerfallow area, with the rate of decrease on the Canadian prairies being 1.26% yr-1 in the Brown soil zone, 7.5% yr-1 in the Dark Brown, and 14.3% yr-1 in the combined Black, Gray and Dark Gray soil zones. The rate of decline in summerfallow area was greater in Saskatchewan than in Alberta, and Manitoba (Black soils only) for unknown reasons. The decline in summerfallow area was accompanied by a steady increase in oilseed crops, especially canola (Brassica napus L.) and, since 1987, in pulse crops, especially lentil (Lens culinaris Medikus) and dry pea (Pisum satiuum L.). Key Words: Seeded area, summerfallow, oilseeds, pulses, cereals

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
