Phosphorus solubilization and pH changes as a result of the interactions between soil bacteria and arbuscular mycorrhizal fungi on a medium containing NH<sub>4</sub><sup>+</sup>as nitrogen source
Bibliographic record
Abstract
This paper reports the effects of Glomus intraradices (Schenck & Smith) external mycelium, mycorrhizal, and nonmycorrhizal transformed carrot roots (alone or in interaction with Pseudomonas aeruginosa (Schroeter) Migula, Pseudomonas putida (Trevisan) Migula, or Serratia plymuthica (Dyar) Bergey et al.) on phosphorus solubilization and pH changes of the medium. All experiments were conducted in a two-compartment Petri plate system with a NH 4 + medium containing an insoluble source of phosphorus (P). In interaction with P. aeruginosa, G. intraradices mycorrhizal roots and G. intraradices external mycelium enhanced solubilization of sparingly soluble sources of phosphates above the levels reached with each culture alone. These improvements were correlated with changes in the pH of the media.Key words: Glomus intraradices, P solubilization, external mycelium, Pseudomonas aeruginosa, Pseudomonas putida, Serratia plymuthica.

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.
