Maritime Provinces Wild Blueberry Fertilizer Study
Bibliographic record
Abstract
Field experiments were carried out over a 4-year period (2001–2004) at one commercial site in each of the Maritime Provinces, Prince Edward Island, Nova Scotia, and New Brunswick. The study was designed to determine the effects of applied fertilizer in sprout year only and in both sprout and crop year on leaf and soil concentration, plant development, and yield. Individually, sprout-year applications of fertilizers ammonium sulfate, di-ammonium sulfate, and 17-17-17 and crop-year application of ammonium sulfate did not affect soil and leaf concentrations, plant growth, or yield. When comparing the mean of fertilizer applications to unfertilized plots, levels of soil, P, K, and S were increased and soil pH decreased and leaf tissue concentrations of N, P, K, and S were increased. Stem length, number of live buds, and number of blossoms were increased; however, yield was not affected in the first cropping cycle and was lowered in the second cropping cycle by applications of fertilizers. Crop-year applications of ammonium sulfate provided no benefit to wild blueberry production.

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.
