Interpretive Summary:

Technical Abstract: The Livestock Nutrient Management Research unit (USDA-ARS-Bushland, TX) is engaged in a national collaborative study by the USDA-ARS Ammonia Production and Deposition from Animal Production Team (ADAPT) to investigate nitrogen transport from CAFO of various types/species (beef, dairy and swine). The ARS-Bushland team collects air samples at and around a cooperating beef cattle feedyard in the Southern High Plains since the summer of 2024. Passive filters targeting airborne ammonia are collected every 2 weeks, with the filters analyzed at the ARS-Bushland laboratory to ensure consistent analyses. Air quality data are analyzed in conjunction with weather data collected from the collocated weather station. Ancillary data such as land use information, livestock inventory, and manure management practices are also collected. The authors will present an update on the data collection and preliminary observations from three consecutive seasons. Data representing all four seasons will be used to improve the U.S. Environmental Protection Agency model intended to estimate ammonia deposition, i.e., the STAGE module (Surface Tiled Aerosol and Gaseous Exchange) in the Community Multiscale Air Quality (CMAQ) model. Results from the ADAPT project can help crop producers with estimating the benefit of ammonia fertilizer deposited from nearby CAFOs.
