Soybean seed costs rose 270% since 1990 but yield gains did not keep pace

The average price farmers pay for a unit of soybean seed increased 270% between 1990 and 2020, with GM seed prices rising 463% over the same period. Today, about 70% of the cost of a bag of soybean seed goes to trait royalties, up from 42% just five years ago. Meanwhile, soybean yield gains have averaged roughly 0.5 bu/acre/year -- a pace far too slow to offset the escalating seed cost on a per-bushel basis. In 2025, USDA projects soybean production costs will exceed revenue by $131/acre, marking a third consecutive year of per-acre losses. Farmers cannot opt out of premium trait packages because seed dealers bundle herbicide tolerance and insect resistance traits together; buying a 'base' soybean variety without stacked traits is nearly impossible through major distributors. The structural cause is extreme consolidation: four companies (Bayer, Corteva, Syngenta, BASF) control the vast majority of the commercial soybean germplasm pipeline, and each prices their trait stack as a take-it-or-leave-it bundle.
