Abstract
Relationships between saturated conductivity (Ks) and separate contents were evaluated from 44 soil series of arable lands: 18 for paddy fields and 26 for upland crop fields.Saturated hydraulic conductivities of A, B, and C horizons were determined with tension infiltrometer and Guelph permeameter in situ.Sand, silt, clay, and organic matter content of each horizon were analyzed.Based on correlation analysis, sand separate had a positive relationship with Ks for both paddy (r=0.27,p=0.017) and upland fields (r=0.24.p=0.030).Clay content had a negative relationship with Ks for paddy soils (r=-0.32,p=0.005) while significant correlation between them was not found for upland crop fields (r=-0.20,p=0.07).Organic matter content showed a positive relationship with Ks only for upland crop fields (r=0.33,p=0.002).Due to low correlation coefficients between separate contents and Ks, performance of pedotransfer functions was not enough to estimate Ks.It implies that hydraulic properties of arable lands were affected by other factors rather than particle characteristics.Platy structure and plow pan were suggested to limit Ks of paddy fields.Soil compaction and diversity of parent materials were proposed to influence Ks of upland crop fields.It suggests that genetic processes and artificial managements should be included in pedotransfer functions to estimate hydraulic properties appropriately.

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
