To amend the Food, Agriculture, Conservation, and Trade Act of 1990 to establish seaweed as a high-priority research and extension area, and for other purposes.

This bill amends the Food, Agriculture, Conservation, and Trade Act of 1990 to establish seaweed as a high-priority research and extension area for which the Department of Agriculture (USDA) may make competitive grants to support research and extension activities. USDA may make grants for carrying out or enhancing research with respect to the harvesting of seaweed for voluntary use for the livestock, poultry, and food animal production industries for purposes of the reduction of methane emissions.

The bill also reauthorizes the USDA high-priority research and extension initiatives through FY2023.
