Abstract
Calcium (Ca) is an element that is considered a macronutrient as higher plants generally contain 5-30 mg Ca/g dry matter (Mengel and Kirkby 1979).Deficiencies of Ca as a nutrient are uncommon (Haby et al. 1990).Neutral and alkaline soils normally contain adequate Ca, while acid soils are usually limed to provide a favourable pH for most crops.Only highly weathered, leached soils under humid conditions are normally low in Ca.It is often difficult to separate the effect of Ca from that of Ca-bearing compounds, such as lime and gypsum.Gypsum often applied as an ameliorant to Na affected soils provides a Ca-related benefit.This benefit can occasionally result from a high pH and bicarbonate-induced Ca deficiency (Rhoades and Miyamoto 1990), however, most of the time is not due to a Ca deficiency, but improvement in soil structure.In western Canada, responses to Ca have been reported in the Peace River Region and East Central Alberta (Figure 1) and are associated with soils of high Na content (Haby et al. 1990).

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
