Abstract
Micronutrient sufficiency ranges are of great importance in crop nutritional diagnosing for improved fertilizer recommendations under field conditions. The objective of this paper was establishing the micronutrients ranges in the cladodes for the evaluation of the nutritional status of ‘Gigante’ forage cactus pear. Micronutrients contents in cladodes and dry matter yield of 72 plots were used. The experiment was composed of four cattle manure rates (0, 30, 60, and 90 Mg ha-1 year-1), three spacings (l.00 × 0.50, 2.00 × 0.25, and 3.00 × 1.00 × 0.25 m), and two production cycles, in a 4 × 3 × 2 factorial plan, designed in randomized blocks, with three replicates. Sufficiency ranges of plots with dry matter ≥ 19.93 Mg ha-1 cycle-1 were determined as well as the mathematical chance for plots with dry matter ≥ 23.75 Mg ha-1 cycle-1 and the critical level. The sufficiency range, critical level and mathematical chance are, respectively, for each micronutrient, in mg kg-1: B, 22.3-32.7; 23.7; 20.36-27.94; Cu, 2.0-3.7; 1.6; 1.8-2.8; Fe, 61.1-126.6; 62.0; 35.8-85.3; Mn, 260.0-507.7; 111.0; 54.8-252.2; Zn, 34.5-57.8; 30.3; 19.7-48.5; and, Na, 29.8-56.2; 19.4; 26.6-42.7. For B, Zn, and Na, the sufficiency range, mathematical chance, and the critical level are adequate; for Cu, Fe, and Mn, the critical level and mathematical chance are more adequate for nutritional evaluation of `Gigante` forage cactus pear, associated with dry matter yield ranging from 21.8 to 31.2 Mg ha-1 cycle-1.

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
