President Trump signed the Agricultural Improvement Act of 2018, the 2018 farm bill, into law on December 20, 2018, after a faster passage than the 2014 bill. The fact sheet outlines commodity programs, conservation, crop insurance and disaster assistance provisions.
The farm bill sets the multiyear framework for commodity support, reference prices and insurance, which shapes planting incentives and farm income that feed into feed grain supply over time. Its near-term price impact is modest because the provisions mainly affect program payments rather than immediate supply.
