Khorezm province, Uzbekistan (lower Amu Darya)
Same water. Better dates.
Three schedules for the same district, on the same canal rules and the same water limit — the state calendar, a diligent trigger rule, and the best schedule the model admits. Solved in this tab, on real 2024 weather and soil.
What this is, and what it is not
The numbers above are computed here, not looked up — reload and they are recomputed from the model. The weather is NASA POWER’s 2024 daily series for the Khorezm zone points; the soil is ISRIC SoilGrids field capacity and wilting point at the same coordinates; the crop response is FAO-56 cotton with FAO-33 stage weighting.
Two honest caveats. Exhaustive proof stops being possible above 22 variables — the larger districts here are solved by heuristics, which find good schedules but cannot prove them, and the page says which is which. And the surveyed parcel boundaries we map elsewhere sit about 27 km from these zone sample points: same province, different district. Conditions here are sampled at the zone points, not the parcels. The benchmark page reports the published gaps separately.
