Study: Liquid Manure Injections Could Reduce Ammonia Emissions

Injecting liquid manure below the soil surface of crop fields could help dairy farmers reduce ammonia emissions, according to a study by the USDA Agricultural Research Service. Based on the study, the process — which injects manure into the subsurface of a field — increased nitrogen capture in the soil and produced a 65 percent lower emission rate than surface broadcast or shallow incorporation.
