Aggregate stability, runoff generation and interrill erosion
Bibliographic record
Abstract
Aggregate stability is one of the main factors controlling topsoil hydrology, crustability and erodibility. A tentative discussion of these topics may start with considerations on the nature of aggregated topsoils and changing microstructures which have a major impact on ponding, runoff generation and erosion by splash, wash. The primary shape of aggregates or peds is often angular or subangular, but after erosion they become more rounded and their transportability and possibly their ‘detachability’ therefore increase. Erosion may also change the aggregate size composition of the topsoil, but little is known about this mechanical aspect of aggregation. The impact of clay particles or clay domains on aggregate stability cannot be summarised in a simple manner, although a positive relationship is most frequently mentioned, for example by Kemper, Koch in the USA and Canada. Soil surface sealing and crusting are two of the key processes controlling runoff generation and rill and interrill erosion, and they are also closely related to aggregate stability.

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.
