Land-use impacts on selected soil properties of the Yungas/Chaco transition forest of Jujuy province, northwestern Argentina: a preliminary study
Bibliographic record
Abstract
Grazing by domestic livestock, firewood cutting, and timber harvesting are the principal uses of the subtropical transition forest located between the humid Yungas and dry Chaco forests at the base of the Andes mountains in Jujuy province, northwestern Argentina. The objective of this study was to conduct a preliminary comparison of selected soil properties between two common land-use systems - deciduous forest rangeland (DFR) and open savanna anthropogenic rangeland (AR) - in the Yungas/Chaco transition forest. Soil organic C and N were measured at a depth of 0-10 cm, while soil penetration resistance was measured at 0-5 and 5-10 cm depths. Soil degradation in the AR was indicated by lower average values for litter cover (56%), soil organic C (28.1 g kg-1), and total N (2.93 g kg-1), and greater soil penetration resistance compared with the DFR (litter cover 94%; soil organic C 45.0 g kg-1, total N 4.45 g kg-1). This created potential for further soil losses from water erosion during monsoon rains and emphasized the need to establish sustainable grazing management practices.

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.
