Abstract
Information on inorganic N content in commercial potato fields in Atlantic Canada is limited. Soil inorganic N measurements were collected from 228 commercial potato fields from 1999 to 2001. Soil NO 3 content to 30 cm depth at planting ranged from 2 to 124 kg N ha -1 , and was generally higher for preceding potato, red clover, or hay crops compared to preceding cereal or other crops. Soil NH 4 content to 30 cm depth measured at planting ranged from 3 to 64 kg N ha -1 , indicating that both soil NO 3 and NH 4 need to be measured to assess plant-available soil N content in spring. Soil NO 3 content to 30-cm depth at tuber harvest ranged from 3 to 250 kg N ha -1 , generally increased with increasing fertilizer N application rate, and differed among different potato cultivars. Soil NO 3 content measured to 30-cm depth in spring ranged from 3 to 100% of soil NO 3 at harvest in the preceding fall, indicating that highly variable losses of soil NO 3 from the root zone occur between growing seasons. Key words: Nitrate, ammonium, Solanum tuberosum L.

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
