What 12 Farm Zones Revealed About a 562-Hectare Field (Part 2 of 2)

In Part 1, we built the framework: 375 H3 Res 10 cells across a 562-hectare Iowa corn field, Moran's I = 0.807, confirming strong spatial structure, and 12 K-Means management zones that cut within-zone soil-nitrogen CV by 66.8%. The zones are built. The cells are assigned. Each row in our DataFrame represents a ~1.5-hectare prescription unit with aggregated soil N, organic matter, pest counts, and mean yield.

Now let's open the hood and look at what those zones actually contain, because the numbers are more interesting than the methodology.

What the 12 Zones Look Like Agronomically

Here's the full zone table. Every number in it comes from the simulation dataset directly.

Soil N (kg/ha)

Soil n CV

Pest Total

Yield (t/ha)

VRT N(kg/ha)

Three zones stand out and demand immediate attention.

• Zones 3 and 6 - over-fertilization candidates:Soil nitrogen at 56.0 and 54.4 kg/ha, respectively, both well above the...
