Abstract
Mineral fertilization of cloudberry (Rubus chamaemorus) has been inconclusive so far. Nutrient absorption of cloudberry was studied by solution depletion 1) to characterize its nutrient uptake kinetics and 2) to determine its preferred nitrogen (N) form. Two accessions, ‘Fjordgull’ (a female cultivar from Norway) and a local wild clonal selection from ‘Baie-Comeau’ (Canada) were tested. Ammonium (NH4) and phosphorus (P) absorption presented a two-component kinetic while nitrate (NO3), potassium (K), and glycine absorption was better fitted with the Michaelis-Menten equation alone. Cloudberry preferences for nitrogen form were in the order: NH4-N, glycine, NO3-N. ‘Fjordgull’ exhibited much higher Km and Jmax for P uptake than the ‘Baie-Comeau’ accession, but they exhibited similar NH4-N uptake kinetics. However, Km values for all nutrients tested except NH4-N were higher than reported for other species. Cloudberry does not appear to have evolved efficient absorption kinetics to compensate for the overall very low abundance of nutrients of peatlands.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
