🌫️ NH₃ Reduction Estimator

Model SF11-S.001

Estimate post-treatment ammonia levels and reduction percentage. Checks OSHA/NIOSH compliance thresholds and flock performance safety zones.

Typical house range: 15–60 ppm
ARS scrubber: 87–99% Β· Acid: ~70% Β· Biofilter: ~55%
e.g., 40 ft Γ— 400 ft = 16,000 sq ft
Broiler standard: 0.65–0.85 birds/sq ft

🏭 Air Scrubber Sizing Tool

Model SF11-S.002

Calculate required airflow (CFM) and number of scrubber units based on house dimensions and ARS 30-minute full-volume air exchange standard.

Typical: 7–10 ft
ARS standard: 30 min Β· High NH₃: use 20–25 min
ARS unit: 4,000–6,000 CFM typical

πŸ§ͺ Nitrogen Recovery Estimator

Model SF11-S.003

Estimate pounds of nitrogen captured daily and annually from scrubber operation. Converts NH₃ captured to urea equivalent for fertilizer credit valuation.

Current house NH₃ before scrubbing
ARS target: 1–5 ppm post-scrubber
Use output from Sizing Tool (SF11-S.002)

🌾 Litter Ammonia Emission Model

Model SF11-S.004

Estimate ammonia emission rate from litter based on moisture, pH, temperature, bird age, and litter type. Predicts house NH₃ levels to justify scrubber installation.

Optimal: 20–30% Β· High risk: >40%
Typical: 7.0–8.5 Β· Higher pH = more NH₃ volatilization
NH₃ increases as litter accumulates over grow-out

🐣 Flock Performance Impact

Model SF11-S.005

Quantify the impact of ammonia on broiler body weight gain, feed conversion ratio (FCR), and mortality. Calculates revenue loss from suboptimal NH₃ conditions.

Performance decline documented above 20 ppm
Typical broiler target: 6.0–7.0 lbs
Industry standard: 1.75–1.95

Why AgrStak 🌾 Poultry Air Quality?

Built on USDA ARS research from Dr. Philip Moore at the Poultry Production & Product Safety Research Unit in Fayetteville, AR. The ARS-patented indoor air scrubber achieves 87–99% ammonia reduction while recovering nitrogen as ammonium sulfate fertilizer. These scientific models help producers document emissions, size systems correctly, and quantify flock performance impacts for better decision-making and regulatory compliance.
