Products are not sold everywhere at once. They are placed where multi-year observation says they belong — region by region, field character by field character.
Two fields inside the same county can ask entirely different things of the same genetics. Averaging them together hides the one answer a grower actually needs.
Regionalized Product Selection is the refusal to flatten that difference. Every placement decision is made against the conditions of the acre in question, using observation gathered in comparable environments.
A product that is right in one region is not automatically right in the next. We treat that as a rule, not an exception.

These are not preferences. They are the conditions a product must be matched against before it is recommended for an acre.

The agronomic questions differ by crop, but the standard does not. Each crop has its own Genetic Fit path so placement reflects your fields rather than a catalog order.
Placement is a decision, not a catalog.
