Climate variability associated with El Niño can create warmer or more humid conditions in some regions. For poultry farms, these environmental changes may increase the difficulty of managing manure moisture, ammonia emissions, and odor, particularly when ventilation and waste handling are not properly coordinated.

Ammonia is mainly produced when nitrogen-containing compounds in poultry manure are decomposed. Higher manure moisture and temperature can influence this process, while insufficient ventilation may allow ammonia concentrations to increase inside or around poultry housing.

Frequent manure removal is one practical management strategy. Manure belts or other automated removal systems can shorten the time manure remains inside the poultry house, helping improve waste-handling efficiency. The appropriate cleaning frequency should be determined according to manure moisture, flock size, house design, and local conditions.

Ventilation management is equally important. Adequate airflow helps remove moisture and gases from the house, while poorly managed ventilation can increase environmental problems. Odor-control equipment, including suitable air treatment or biofilter systems, may provide additional support where local conditions require it.

Biological odor-control products may also be considered, but their effectiveness can vary with temperature, moisture, application method, and manure characteristics. Farms should evaluate such products through site-specific testing rather than assuming identical results across different regions.

Overall, effective ammonia management requires a combination of manure removal, ventilation, moisture control, and appropriate odor-treatment measures. Climate conditions should be considered when developing seasonal waste-management plans.
