Crop Optimal Ranges — the ALUES set
The optimal requirement value for every crop in the ALUES 0.2.1 reference database, across ten key suitability elements. Each figure is the crop's S1 band; the bar beneath shows where that band sits within the range of all crops — so the demanding and the tolerant read at a glance.

Reading a cell. The figure is the crop's optimal (S1) value or range. The bar shows its position across all 50 crops — a bar to the left means low tolerance, to the right means high — letting you scan a whole column for the crops that suit a given site.
