Species: Poultry (Broiler and Turkey)
Use Area: Animal Housing
Technology Category: Chemical Amendment
Air Mitigated Pollutants: Ammonia

System Summary

Klasp™ has been shown to be an effective litter amendment for minimizing ammonia concentrations, decreasing litter moisture, and sequestering nitrogen and phosphorous. Klasp™ efficiently lowers litter pH while providing a drier house environment. Klasp™ is effective in reducing and holding in-house ammonia levels below 25ppm during the first 14 days of grow-out leading to providing an improved bird environment and improved bird performance.

Application rates of Klasp™ are dependent on management practices and needs. Typical rates will range from 34 to 56 kilograms per 93 m2 (75-125 lb/1000 ft2). The length of ammonia emission control increases with increasing application rate (Ritz et. al, 2007). Heat is not required to activate Klasp™ prior to bird placement. This mode of activation provides producers application flexibility and improved time management by allowing the product to be applied up to 4 days prior to bird placement.

Applicability and Mitigating Mechanism

  • NH3 volatilization from litter is dependent on pH, moisture content, air velocity, NH4 concentration, and temperature.
  • Klasp™ applications reduce litter pH and lowers NH3 emission
  • Litter pH affects NH3 volatilization
  • Klasp™ may be applied to the litter before bird placement

Limitations

  • Moisture is needed to activate Klasp™, as a result, extremely dry houses may influence performance
  • Applications rates will depend on current management practices and needs, along with seasonal temperatures
  • Application costs are subject to the proximity of the producer to the chemical distributor

Cost

Cost is dependent on several factors. The producer’s proximity to the chemical distributor, application rate, and use cycle of KlaspTM will contribute to the final per house cost.
