Effect of phosphorus application on wheat yield and phosphorus uptake in a Brown Chernozem in southern Saskatchewan
Bibliographic record
Abstract
The 2015 site was located near Central Butte, Saskatchewan on a loam textured Brown Chernozem canola stubble.Trials were set up on an upper slope and lower slope position.The pH of upper slope and lower slope was 7.2 and 6.5 respectively while MK extractable P was 15 and 16 mg P kg -1 in the 0-15 cm depth. Phosphorus was applied as monoammonium phosphate (11-52-0).All plots received a blanket application of N at 100 kg N ha -1 . No detectable differences were observed among P fertilizer application methods or rate.The broadcast P at the 80 kg ha -1 rate did have a more severe kochia infestation, providing an explanation for the low mean yield in this treatment. The marginal soil available phosphorus level is consistent with lack of a large response to added P fertilizer at the site in 2015.

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; a candidate call from one teacher head, not a consensus.
