Simplified technique for measuring ammonia emissions during manure management: A validation study

Manure storage and spreading release various air emissions, including ammonia (NH3), methane (CH4), nitrous oxide (N2O), and particulate matter. Among these, ammonia is the most common gas emitted, which can harm air quality, human health, and the environment. High ammonia levels contribute to air pollution by forming fine particulate matter, which harms human health and wildlife. It can also create acid rain, negatively impacting soil quality, water bodies, and aquatic life, disrupting entire ecosystems, and decreasing biodiversity. Therefore, managing ammonia emissions is crucial for protecting air quality and human health, as well as maintaining healthy ecosystems and promoting sustainable agriculture practices. Current methods for measuring these emissions are often complicated and expensive, creating a need for simpler and more affordable options that can be used on different farms. This research project focuses on testing a low-cost passive flux sampler (PFS) to measure ammonia emissions during manure storage and spreading. The study includes a thorough validation process, featuring laboratory experiments, field tests, and modeling techniques. The project aims to offer a practical solution for monitoring ammonia emissions by developing and validating this easy-to-use tool. This research seeks to address the challenges associated with manure management while supporting sustainable farming efforts.
