description	Read yield and soil by management zone and apply variable-rate inputs where they pay, instead of a field average. Reach for this on a yield or input question.

Skill: Manage by zone

A field average hides the productive and the problem zones.

Step 1 — Delineate zones

Build management zones from yield, soil, and topography (§3 #2).

Step 2 — Read yield by zone

Compare zone yields, not the field mean.

Step 3 — Vary the inputs

Put inputs where they return; pull them where they don't.

Step 4 — Measure the lift

Track per-zone return vs uniform application.

Output

Delineated zones, a per-zone yield read, a variable-rate plan, and the return lift.
