Abstract
The application of phosphogypsum as a bioameliorant for the restoration and rational utilization of compacted gray soils, saline, and degraded lands has gained increasing importance due to the need to mitigate the technogenic impact on the environment caused by industrial waste.This study aimed to investigate the potential of phosphogypsum as an alternative means for restoring compacted gray-earth soils in degraded and saline irrigated lands.Field experiments were conducted to assess the effectiveness of phosphogypsum application from both production and agroecological perspectives.Various doses of chemameliorants were applied to compacted gray-earth degraded and saline soils, and the optimal conditions for restoring soil fertility were determined under experimental field settings.It was observed that the use of phosphogypsum reduced the necessity for mineral fertilizers.Furthermore, phosphogypsum application was found to improve soil structure, resulting in an increase in humus content by 59.0-82.2%.The soil's ability to retain moisture was also enhanced, with an increase in porosity ranging from 20% to 30%.In the root zone, phosphogypsum created conditions conducive to crop production, with salinity levels decreasing by 50-75%.These findings suggest that phosphogypsum can be effectively employed as a soil amendment for enhancing fertility in compacted gray-earth soils during comprehensive land reclamation efforts.

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
