Enhancement of the three-dimensional interfacial layer of a rocky desertification soil using a red mud-based fertilizer
Bibliographic record
Abstract
Red mud, a solid waste of alumina extraction from bauxite, was used as a compost carrier to prepare a geological fertilizer. It was amended at proportions of 0, 5%, 10%, 15% and 50% by weight (g/kg) to improve a rocky desertification soil (classified as lime soil) productivity. Through the simulation of different rain intensity (15, 50, and 90 mm/h) with three precipitation rates (1000, 2000, 3000 mm), soil chemical and physical properties, such as soil organic matter (SOM), total nitrogen (TN), ammonia nitrogen (AN), nitrate nitrogen (NN), total potassium (TK), available potassium (AK), total phosphorus (TP), available phosphorus (AP), bulk density and aggregates were tested and analyzed. In addition, a three-dimensional evaluation and analysis of the improvement attributed to the geological fertilizer was conducted. The results showed that the soil loss could be maintained in the range of 19%–72% under rainfall intensities. In addition, the reduction rate of soil clay content was less than 20%, and the lowest reduction rate of SOM, TN, TP and other nutrient was only 4% at the application rate of 5%–50%. The BD of the 0–20 cm top soil decreased progressively from 1.2 to 0.9 g/cm 3 , while the water-stable aggregate volume increased by 45%–76%. The red mud-based fertilizer enhanced the ability of the rocky desertification soil to resist rainfall erosion and infiltration in amended soil profiles. Considering the trends of nutrient losses and effects on the soil structure, the application rate of 15% by weight (g/kg) was best for improving the rocky desertification soil productivity.

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.
