Root Growth of Apache Plume and Serviceberry on Molybdenum Mine Overburden in Northern New Mexico 1
Bibliographic record
Abstract
This study evaluated root growth of Apache plume (Fallugia paradoxa) and Saskatoon serviceberry (Amelanchier alnifolia) on overburden at the Molycorp, Inc. Mine near Questa, NM. Container grown, 1-year-old seedlings were transplanted, and either fertilized or not fertilized at the time of planting in August 1995. Survival and shoot growth were monitored in 1996 and 2000. Root density was determined at three distances (planes) from the base of the plant at six depths in 2000. Fertilization effects on serviceberry root densities were depth dependent. Total root density of unfertilized plants was greater than fertilized plants. Serviceberry total root density differed among planes (distances from base of plant) between fertilization treatments. Fertilized plants had fewer roots in the 10-cm plane relative to the 20- and 30-cm planes. Fertilized plants of Apache plume had higher total root densities at depths >20 cm within the 20-cm plane than plants not fertilized at time of planting. Although overall performance in terms of shoot growth was positive for both species, survival was generally low and root density varied when fertilized at time of planting. Factors including fertilizer characteristics, planting date, and site conditions may have influenced species performance.

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.
