About this chart: This is the weekly chart of the price ratio between November 2026 soybeans and December 2026 corn. In the spring of 2025, this ratio was between 2.40 and 2.46. This resulted in corn and soybean acreage coming in close to trade estimates in the March 2025 Prospective Plantings report. In the 2025 crop year, we had an early spring, with increased corn acres and reduced prevent-plant acres. This year the soybean-to-corn price ratio is moving higher, encouraging more soybean acres.
What does this mean for you: If the ratio moves above 2.5, then expect increased soybean acres and less corn.
