Abstract
An extensive literature review was conducted of corn and soybean research that compared yields of no‐tillage to conventional fall tillage systems. The objective was to test the hypothesis that no‐till has a different effect on corn and soybean yields in different regions of the United States and Canada. The trial results were mapped to look for geographic and environmental patterns in the relative performance of no‐tillage to conventional tillage on corn and soybean yield. The national average difference in corn and soybean yield between no‐tillage and conventional tillage was negligible. A map of the tillage yield comparisons was created for the U.S. and Canada. No‐till tended to have greater yields than conventional tillage in the south and west regions. The two tillage systems had similar yields in the central U.S., and no‐till typically produced lower yields than conventional tillage in the northern U.S. and Canada. No‐tillage had greater corn and soybean yields than conventional tillage on moderate‐ to well‐drained soils, but slightly lower yields than conventional tillage on poorly drained soils. Corn and soybean yields tended to benefit more from crop rotation in no‐till as compared to continuous cropping. Future tillage research should focus on optimizing successful high residue no‐tillage or strip‐tillage production systems instead of making comparisons to conventional tillage systems.

Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
