Abundance and diversity of nematodes and microarthropods in established and newly converted agricultural soils in western Newfoundland and Labrador
Bibliographic record
Abstract
Nematodes and microarthropods are used as indicators of nutrient flow through complex soil food web interactions and thus are indicators of soil health. In this study, nematodes and microarthropods were extracted from natural and farmed land at two locations in Newfoundland and from biochar treated soil at one location in Labrador. Newfoundland soil had several combinations of crop and manure treatments. All soils were analysed for various abiotic soil fertility parameters. Farmed soil had a more stable and complex nematode community than adjacent natural soils. Manure application did not have an obvious impact on nematode composition but affected the microarthropod community. Biochar treatment resulted in changes to faunal composition and abundance though microarthropod populations were not well established in Labrador soils. Nematode and arthropod compositions were more strongly reflective of variations in soil pH than other measured parameters. All systems had bacterivore dominated nematode communities, an indication of bacterially driven soil metabolism.

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.
