Abstract
Biomass is produced as a feedstock for energy generation and industrial processes from short-rotation woody crop plantations in Europe, the USA, and Canada. This study determined the impact of soil enrichment on the survival rate, productivity, energy value, and yield of three species of crops grown on poor soil in a 4-year harvest rotation based on two factors: species (willow, poplar, and black locust) and fertilization (lignin, mineral fertilization, mycorrhiza inoculation, and their combination). The highest average yield was obtained from willow, followed by poplar and black locust. The highest yield in the entire experiment was for poplar with lignin combined with mineral fertilization (10.5 odt ha −1 year −1 ). Using lignin combined with mineral fertilizers increased the yield by 8–14 % compared to mineral fertilizers alone for willow and poplar and nearly doubled the black locust yield. The energy value of the yield ranged from 28.6 to 176.7 GJ ha −1 year −1 , respectively, for black locust grown on the control plot and for poplar grown with mineral fertilization combined with lignin.

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 it
