Abstract
The Least Limiting Water Range (LLWR), is defined as the range of water contents in which aeration, water and soil resistance are the least limiting for plant growth. It was hypothesized that the LLWR and water contents measured outside of the LLWR would explain much of the variation found in yield and yield response to fertilizer N. Water contents, soil properties and yields were measured on 12 sites across southern Ontario. Results showed that the LLWR parameters were poor predictors of the variability in yields. Many observed water contents were also found to be less than the wilting point. Kay et al. (1999) defined a lower water content limit based on the cessation of photosynthesis ([theta]0p). This study determined that the difference between water contents and [theta]0p (plant extractable water) correlated well with yield. Organic carbon was significantly correlated to yield and yield response, and improved yields under drought and saturated conditions.

Full frame distilled prediction
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
