BELTSVILLE, Md. — Capturing and recycling ammonia from livestock waste is possible using a process developed by USDA researchers.
This invention could help streamline on-farm nitrogen management by allowing farmers to reduce potentially harmful ammonia emissions and concentrate nitrogen in a liquid product to sell as fertilizer.
The work was conducted by Agricultural Research Service scientists Matias Vanotti and Ariel Szogi at the agency’s Coastal Plains Soil, Water and Plant Research Center in Florence, S.C. ARS is the USDA’s chief intramural scientific research agency.
The system uses gas-permeable membranes that are similar to materials already used. . .
