Abstract
The influence of phytoextraction in arsenic (As) contaminated soil on the phosphate and citric acid addition were investigated using Pteris vittata L. (Chinese brake fern). The As uptake in the fronds increased 85% in As-spiked soil when phosphate was added. The addition of citric acid for 2 weeks to the phosphate added soils resulted in the highest As uptake by 75% compared to only phosphate treatment. The Zn concentrations in fronds also increased 31-fold in phosphate added soils and 60-fold in 2-week citric acid added soils without phosphate treatment. The extractable arsenic species in the fern fronds are 71% of As (III) and 29% of As (V), respectively.

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
