Poultry Manure Characteristics
Manure properties:
• High nitrogen values
• Moisture content: 65-80%
Ammonia volatilization:
• Moisture content
• pH
• Temperature
![Page 4: Poultry Manure Belt Drying - Alberta.caDepartment/deptdocs.nsf/all/... · Poultry Manure Belt Drying 2017 Manure Management Update Jesse Vandenberg Alberta Agriculture and Forestry](https://reader034.vdocument.in/reader034/viewer/2022052613/5f22fff91da215796b3b6be1/html5/thumbnails/4.jpg)
Ammonia Volatilization:
Reasons for Concern
• Poultry heath/production
• Worker health
• Cost of control
• Loss of nitrogen value
from manure
• Impact on local
environment
• Odour
• Acidification of water/soils

Ammonia Volatilization Controls
• Diet/Water
• Supplements/enzymes
• Manure pH
• Manure drying
• Belt dryers
• Tunnel dryers

Project Background
Project initiated in 2016
• Egg Farmers of Alberta
• Alberta Agriculture and
Forestry
Information gaps noted
• Economics
• Applicability in Alberta
• Aviary applications
![Page 7: Poultry Manure Belt Drying - Alberta.caDepartment/deptdocs.nsf/all/... · Poultry Manure Belt Drying 2017 Manure Management Update Jesse Vandenberg Alberta Agriculture and Forestry](https://reader034.vdocument.in/reader034/viewer/2022052613/5f22fff91da215796b3b6be1/html5/thumbnails/7.jpg)
Project Goals
• Improve understanding of the
benefits and challenges of adopting
drying systems
• Study variables that impact ammonia
release and nutrient retention
• Investigate economic and net
environmental implications

Current Activities
Survey of producers
with belt drying
Manure sampling
• Fresh
• Dried vs. Air Dried
Analyze manure and
water samples
![Page 9: Poultry Manure Belt Drying - Alberta.caDepartment/deptdocs.nsf/all/... · Poultry Manure Belt Drying 2017 Manure Management Update Jesse Vandenberg Alberta Agriculture and Forestry](https://reader034.vdocument.in/reader034/viewer/2022052613/5f22fff91da215796b3b6be1/html5/thumbnails/9.jpg)
In-Barn Testing
Perform in barn tests to
evaluate:• Extra energy usage
• Manure nutrients levels
• Ammonia levels in barn
• Other co-benefits/challenges
Scenarios to optimize:• Drying time
• Manure removal frequency
• Seasonal optimizations

Sustainability Perspective
Compare net cost/benefit
• Extra energy to dry
• Potential emission reduction
• Retention of nutrients in manure
• Ventilation/heating impacts
Beyond only economic analysis

Evaluation of Ammonia
Emissions
• Contingent on in-barn
testing
• University of Alberta
Poultry Research Centre
• Measure relative Ammonia
and GHG emission
• Use to guide
recommended Best
Management Practices
