FD-CIC Nutrient Management: Fertilizers, Inhibitors, Biologicals, and Yield Claims
Separate agronomic value from the exact pathway by which a product or practice can affect an official FD-CIC result.
Reviewed
Direct answer
A nutrient-management product does not automatically lower an official FD-CIC result merely because it is used. The claim must identify the exact official input, permitted definition, documented rate or outcome, supporting records, and timing. A product can have agronomic value without creating a separate FD-CIC input.
