<i>Swine Manure: A Geochemical Perspective</i>
Bibliographic record
Abstract
Abstract. Â This study characterized the solution chemistry found in seven swine manure storages in Saskatchewan, Canada in regard to the solution as a source term for potential contaminant transport study and modeling. The species of most concern in EMS seepage is nitrogen. Ammonium nitrogen is the most abundant form of nitrogen and one of the most abundant ions in the EMS effluent studied. Potassium and sodium may be cations of concern as they will likely compete with ammonium for soil exchange sites, which in turn will affect attenuation of ammonium. Bicarbonate and chloride are the most abundant anions (bicarbonate >> chloride). High concentrations of bicarbonate will likely affect precipitation of carbonaceous minerals and may affect solution pH. EMS ponds contain a solution composed of, as a percentage of total molal concentration, 36% ammonium, 36% bicarbonate, 8% potassium, 6% chloride, 5% sodium plus sulphate, calcium, magnesium and other nutrients. Additionally, the solution also contains approximately 6,000 mg/L organic and 9,000 mg/L inorganic carbon and has a near neutral pH. As a result, the solution has a low Eh resulting in nitrogen remaining in the ammonium-N form.

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; both teacher heads agree on what is shown here.
