In-woods chipping: Possible evidence for allelochemical interaction of leachate generated from trembling aspen (<i>Populus tremuloides</i> Michx.) bark and wood waste
Bibliographic record
Abstract
A portable delimber-debarker-chipper, designed for in-woods chipping operations, was used to produce waste bark and wood residue from winter-harvested tree-length trembling aspen logs. The residue was then utilized to create leachate, which was subsequently used to treat white spruce, lodgepole pine, paper birch, aspen and Calamagrostis canadensis seedlings grown in sand-filled pots. Treatment with the leachate significantly decreased height growth and shoot and root dry weights of all species relative to the control treatment. Root: shoot ratios of all tree species except lodgepole pine were increased significantly by application of leachate. The root: shoot ratios of treated C. canadensis were significantly increased during one season, but significantly reduced in the following season. The data indicated that leachate from aspen bark and wood residue contain allelochemical properties that could affect the regenerative capacity of aspen cutblocks harvested for in-woods chipping operations. Key words: aspen, leachate, allelochemistry, Populus tremuloides, in-woods chipping

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
