Radical-induced rapid humification of waste milk and the performance of derived slow release fulvic-like fertilizer
Bibliographic record
Abstract
Abstract The direct disposal of waste milk (WM) leads to severe environmental pollution and resource loss. Considering the high content of nutrients, WM has a potential as an ideal raw material for organic fertilizer. In this work, base-activated persulfate (KOH/PS) was used as a new artificial humification technology to transform WM into product with 45.3% of fulvic-like acid (FLA) and 18.9% of humic-like acid (HLA) in 1 hour. Therein, FLA had more active groups (-COOH, -CNOH, -OH) than natural fulvic acid likely owing to hydroxylation, carboxylation and the Millard reaction. Reactive species of •OH and SO 4 − • generated in KOH/PS system may be related to degradation or polymerization reactions during humification. The product was mixed with attapulgite to fabricate a slow-release nano FLA fertilizer which could increase the yield of chickweeds by 107% compared with the blank as well as the abundance of beneficial bacteria in soil. Overall, this study provided a rapid method for the recycling of waste food and highly-concentrated organic wastewater, which may have a huge application prospect in sustainable agriculture.

How this classification was reachedexpand
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.
