# When the River Runs Low, Southern Grain Farmers Pay the Most - Oklahoma Farm Report

> Researchers Zhang et al. (2026) find that higher barge freight rates are passed back to farmers through weaker local corn and soybean basis. The effect varies by region and crop, and Mississippi River low water in late 2022 is cited as the example of the shock. Elevators widen the gap between Gulf values and their farmgate bids.

## Why it matters

Higher barge costs lower cash bids for interior grain, so farmers near constrained river segments receive less for corn and soybeans even when futures are unchanged. Feed buyers in those regions may see cheaper local grain but higher delivered costs.
