Abstract

fetched live from OpenAlex

Cultivation of switchgrass (Panicum virgatum) and miscanthus (Miscanthus spp.) as dedicated biomass crops on Ontario’s marginal agricultural lands is increasing, and producers are seeking opportunities to enhance the sustainability of their operations. Therefore, we conducted a field study addressing the knowledge gap regarding field scale agronomic and environmental impact of four biofertilizers compared to a synthetic nitrogen fertilizer and a control for mature switchgrass and miscanthus. Biomass yield, plant morphology, soil fertility and biological health, and greenhouse gas fluxes were measured. Synthetic nitrogen and AGTIV® biofertilizer produced the highest yield for switchgrass and miscanthus, respectively. AGTIV® and Optimyc + MooR also increased bacterial and fungal gene abundance in the top 10 cm of soil under switchgrass cultivation in 2020. All fertilizers increased the release of key macronutrients under controlled conditions. In conclusion, this research shows that certain biofertilizers may be an alternative option to synthetic fertilizers for biomass crop production.

Full frame distilled prediction

Teacher imitation

Not 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.
