Brief Description
This is the Study 1 of the project "Assessment of the Effectiveness of Carbonized Rice Hull (Activated and Un-activated) on Odor Emission, Bio-aerosol Concentration, and Fly Population of Some Agricultural Operations".
This study involves two major components:
1. Laboratory testing - the study will be initially conducted in a bench (laboratory) scale for manageability and to minimize costs. Results will serve as a reference for field-scale testing or validation. This study will employ 5 treatments, 3 replications using the Randomized Complete Block Design (RCBD). However, an increase in the sequence of treatments (more levels) will be tried if the effects of the 2 initial levels are found promising. Hence, the treatments are the following:
- Control (no treatment)
- Un-activated carbon from CRH (2 levels) - topical application
- Activated carbon from CRH (2 levels) - topical application
2. Field testing - to validate the results of the laboratory testing, this will be tested in an actual poultry facility. The most promising level both from un-activated and activated CRH treatments will be considered in the field test, hence it will have 3 treatments replicated 3 times using RCBD. The following treatments therefore will be:
- Control (no treatment)
- Un-activated CRH (1 level) - topical application
- Activated CRH (1 level) - topical application
Parameters to be assessed
- Odor emission - nasal ranger
- NH3 - detector tubes
- VOCs - continuous VOC analyzer
- Fly population - Fly traps
- Bio-aerosols - real time analyzer (e.g., wide-issue bio-aerosol sensor (WIBS))
- Other associated effects (e.g., manure quality, economics, etc)
