Abstract
Patel, R.M., Prasher, S.D. and Bonnell, R.B. 2000. Effects of watertable depth, irrigation water salinity, and fertilizer application on root zone salt buildup. Can. Agric. Eng. 42: 111-115. Salt buildup due to irrigation water salinity and fertilizer application was studied in field Iysimeters planted with green peppers (Capsicum annuum).Waterwas applied by subirrigation, and the fertilizers were incorporated at the soil surface. Three subirrigation water salinities, I, 5, and 9 dS/m and two watertable depths, 0.4 and 0.8 m, were used. The soil salinity was determined by first measuring the bulk soil salinity by time domain reflectometry (TDR) and then converting it to soil solution salinity (ECsw)' It was found that the salinity of the subirrigation water affected ECsw in the upper soil profile when the watertable was maintained at 0.4 m depth. The subirrigation water also affected the lower half of the soil profile when the watertable was maintained at 0.8 m depth; however, it did not affect any salt buildup in the upper half. Also, the addition of N, P, and K fertilizers did not contribute to the salt buildup in the soil. Although watertable depth and subirrigation water salinity affected ECsw' they did not affect the green pepper yield. The experiment was conducted using field Iysimeters filled with a sandy soil and covered with a plastic sheet to simulate arid conditions. Therefore, caution should be exercised in extrapolating the results of this study to field conditions and other soils.

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
