Fate of limestone dissolution products in acidic metalcontaminated soil mesocosms
Bibliographic record
Abstract
The impact of liming (10 t ha-1 of calcitic and dolomitic limestone, separately) on the soil \nsolution and soil matrix was investigated in an acidic metal-contaminated soil from Sudbury, \nON. A soil mesocosm experiment was performed; columns were leached with simulated \nrainwater and the soil solution collected at various locations throughout the soil column. The \ndissolution rate of calcitic limestone used for this experiment was found to be approximately \ndouble that of the dolomitic limestone investigated. Calcium and Mg released during limestone \ndissolution migrated through the soil profile to the Bf-BC interface. The addition of limestone \nincreased the pH and decreases the bioavailability of Ni, Cu, Co, Cd, As, Ba, Mn, and Zn the \nLFH horizon. Amending acid, contaminated soils with calcitic or dolomitic limestone has \nprofound effects on soil solution chemistry.

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.
