Along with industry and transportation, agriculture is one of the main sources primary particulate matter (PM) emissions worldwide. Bioaerosol formation PM release during livestock manure field application associated threats to environmental human health are rarely investigated. In temperate climate zone, fertilization seasonally contributes local air pollution regularly twice per year (spring autumn). Measurements in a wind tunnel, computational fluid dynamics (CFD) simulations were performed analyze aerosolization poultry influence moisture content treatment. A positive correlation between dry (DM) was observed. Therefore, treatments strongly increasing DM should be avoided. However, high led reduced microbial abundance and, therefore, lower risk pathogen dispersion. Considering findings measurements, optimal range for identified as 50–70%. Maximum PM10 concentrations approx. 10 mg m3 measured spreading dried (DM 80%), concentration that classified harmful. The modeling processes indicated low beyond distance 400 m from source. detailed knowledge about improved this study, enabling management optimization pathogenic into environment.
