Abstract

fetched live from OpenAlex

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

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
