Effects of parent material and climate on the magnetic susceptibility of Saskatchewan soils
Bibliographic record
Abstract
Magnetic susceptibility (χ) of soils is easily measured; however, the link between magnetic horizonation and pedogenic factors needs to be clarified. This study compares the χ of the A and C horizons of 89 generally well-drained profiles from the agricultural area of Saskatchewan to quantify the effects of parent material and climate. Total Fe and Mn were only weakly related to χ, but χ increased as the soil texture became coarser. This trend was more noticeable in parent material than topsoil samples, and stronger for till than for fluvial, lacustrine and aeolian parent materials. The A horizon samples showed enhanced low frequency and frequency dependant χ. This increase in topsoil χ was greatest in the more humid areas. Key words: Magnetic susceptibility, parent material, climate, texture, magnetic enhancement, soil zone

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.
