Abstract
Correlations and non-linear regression analyses were used to determine the optimal rate of fertilization that would maximize production of grain while minimizing effects on the environment in Jiangsu Province, China. Correlation coefficients between the amounts of cereal grain produced and rates of fertilization were 0.880, 0.606, and 0.212 for the periods 1970-1983, 1984-1997, 1998-2011, respectively. Current amounts of chemical fertilization used are causing adverse effects on the environment. By use of simulation analyses, it was determined that 550 - 600 kilogram of fertilizers (a mix of N, P 2 O 5 , K 2 O) per hectare is the upper limit amount of fertilization that balances production and potential for eutrophication in Jiangsu. Amounts of fertilizer applied are greater in the North of Jiangsu Province with three-fold more fertilizers applied than in the south. Factors such as proportion of farmers in the regional population, incomes of farmers, multiple cropping index, proportion of land irrigated, proportion of land in agricultural production all influence the amount of fertilizers applied in this region.

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 it
