Transformation of Phosphorus in Forest and Savannah Agro-Ecological Alfisols incubated with Different Phosphorus Fertilizers, in Ekiti state, Southwestern Nigeria
Bibliographic record
Abstract
Experiments on incubation with phosphorus (P) changes in two Nigerian Alfisols, were evaluated on the effectiveness of P sources (ground phosphate rock, GRP-9% P, Pace-setter Organo-Mineral Fertilizer (PR-fortified P-S-OM, 11% P and single superphosphate, SSP-7.7% P, for reference). All samples were adjusted to water tension measured at M Ψ w = 0.03 MPa. Changes in applied P were evaluated at 2, 6, 12 and 24 weeks after which data were analyzed using analysis of variance and correlations. Over 24 weeks of incubation, SSP transformed mostly into iron (Fe)-bound P and GPR produced the highest inorganic phosphate ions and transformed largely into the soluble and more chemically stable residual P, in both soils. This fraction, had high and positive correlations (r = 0.69, p < 0.05) with soil properties and constituted a major source and sinks of plant available P. Thus, GPR contributing beneficial effects of residual phosphates.

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.
