Abstract
Le fumier et le compost sont des alternatives économiques aux engrais commerciaux, mais vous êtes peut-être assis sur un autre trésor qui se trouve dans votre terre et qui ne demande qu’à être utilisé : les roches phosphatées inorganiques. Utiliser la roche n’est pas nouveau en soi. Dans de nombreuses usines à travers le monde, les roches phosphatées sont traitées chimiquement (avec de l’acide sulfurique par exemple) pour dissoudre le phosphate et l’utiliser comme engrais pour les cultures. Au milieu des années 90, des chercheurs de l’Institut de recherche minière du Zimbabwe et de l’Université de Guelph au Canada ont mis au point un engin qui permet d’obtenir, en mélangeant des roches phosphatées avec un triple engrais super-phosphaté, des pastilles propres et faciles à utiliser. Une fois les pastilles répandues sur le sol, il suffit de les arroser pour qu’elles libèrent leur phosphate.\n\n\n\nDepartment of Land Resource Science\n\nUniversity of Guelph\n\nGuelph, Ontario\n\nCanada N1G 2W1\n\nFax : +1 519 824 57 30\n\nEmail : pvanstra@lrs.uoguelph.ca

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
