Annual forage insurance: Policy basics and examples for water-limited operations

Annual Forage Insurance (AFI) can help producers manage rainfall risk for annual crops used as forage, hay, or silage. This precipitation-based policy may be especially useful in drought-prone areas or under irrigation limits. The sign-up deadline for the 2026 commodity year is July 15, 2025. This article outlines key policy decisions, examples for water-limited systems, and AFI use trends in Kansas.
