Abstract
Abstract Land‐use practice shift in the wetland riparian zone can influence groundwater table (GWT) fluctuations and salts dynamics, potentially leading to soil salinization. The risk of soil salinization linked with high water tables could be better managed by using high growing capacity and deep‐rooted phreatophytic vegetation via the 'biodrainage' approach. We evaluated the impacts of short rotation willow (SRW; Salix dasyclados Wimm.) plantation on soil and groundwater salinity linked to shallow GWT fluctuations and compared with adjacent annual crop (AC) and pasture (PA) in a field experiment. Groundwater salinity (EC gw ) along with depth to GWT and soil salinity (EC soil at 0–60 cm depth) were measured along transects within each land‐use practice in two Prairie Pothole Region (PPR) wetland sites (A and B). The variations in EC gw were significant ( p < 0.05) across land‐uses; however, inconsistent in both sites. The positive correlation with EC gw , EC soil, and total dissolved salts (TDS) indicated higher salinity and salt accumulation with increased depth to GWT in both sites. The EC soil varied significantly ( p < 0.05) among land‐use practices; however, land‐use patterns were not consistent in both sites. Throughout the experimentation, site B consistently exhibited higher EC soil (two‐fold) than site A. We observed a decreasing inclination in EC soil with increasing SRW biomass at both depths (i.e., 0–30 and 30–60 cm) and vice versa. This study refines our knowledge of SRW plantation‐linked potential hydrological alteration and its implication on salinity, which provides a critical context for degraded marginal riparian wetland soil management in the PPR.

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
