Agriculture Improvement Act of 2018

The Agriculture Improvement Act of 2018 was enacted in 2018 as P.L. 115-334 and was scheduled to expire in 2023, spanning 12 legislative titles that cover commodity support, conservation, crop insurance, nutrition assistance (SNAP), research, rural development, forestry, energy, horticulture, and trade. The Congressional Budget Office scored the total cost at approximately $428B over the authorization window, with the overwhelming majority of outlays flowing to nutrition programs rather than farm payments, a consistent pattern across modern Farm Bills. These figures are drawn from Congressional Research Service reports and USDA Economic Research Service tracking of Farm Bill outlays.

Key provisions of this bill - Hemp legalization, CRP cap raised, dairy margin coverage - illustrate the policy priorities of the Congress that passed it. Farm Bills are best understood as omnibus legislation: each one bundles the farm safety net (ARC, PLC, marketing loans), conservation programs (CRP, EQIP, CSP), crop insurance modifications, SNAP eligibility and benefits, and dozens of smaller programs into a single reauthorization vote. The structure means that changes to the nutrition title, which covers more than 75% of a typical Farm Bill's cost, often drive the politics of the whole package, with agricultural provisions negotiated as part of a broader rural-urban legislative coalition.

Reading a Farm Bill in isolation misses its impact. The 2018 authorization set the rules that determined how much each state received in commodity, conservation, and disaster payments during its effective years, the cumulative figures visible on the state pages of this portal are the direct outputs of those statutory formulas.
