Abstract
This paper shows the results obtained when evaluating current practices in cultivation processes of nopal. Production of nopal in the borough of Milpa Alta in Mexico City has been based for more than 40 years on the use of high doses of fresh cow manure (up to 600 t ha-1). It is necessary to consider the effects that this type of fertilization could have on the environment. In order to compare the effect of different fertilization methods on the production, quality and shelf-life of cladodes, three-year-old cactus plants were fertilized with compost, compost leachate, fresh manure cow and synthetic fertilizer; plants treated with water served as a control. The plants fertilized with compost (leached or solid) tended to a higher yield (g) per plant, although there were no significant statistical differences between treatments. Cladodes produced with solid compost or fresh manure showed a lower pH (4.7) than those produced with water to the soil. Cladodes produced with synthetic fertilizers showed higher shear strength than those produced with manure. Cladodes produced with synthetic fertilizer and compost leachate took more days to show shelf darkening (oxidation) than those produced with soil water. In addition, the use of compost showed a significant impact on cost reduction during the production nopal given a lower cost against manure and synthetic fertilizer.

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
