1. Animal Waste Management:

2. Objectives:
To gain an understanding to why waste management is important
To understand different types of waste disposeal
To understand laws regarding waste disposal

3. Trends: Farms are increasing in size
The amount of animal waste is increasing
Farmers must find new ways to manage animal waste

4. Laws:
Public Health Act.
Environmental Management Act of 2005.

5. WHY IS WASTE MANAGEMENT Important?
‘Clean and green’ agriculture is now of increasing importance in the marketing produce, both domestically and overseas.
Appropriate management of farm wastes can benefit farm by preventing:
contamination impacting property value
contamination of the land and water on your farm
breeding sites for disease spreading mosquitos, pest animals and predators
contamination of produce
stock injury, disease or death
offensive odours
large penalties and clean-up costs from poor waste management.

6. If not managed properly, agricultural waste from farm operations can pollute the environment resulting in impacts to water quality and a general loss of aesthetics.  
The degradation of water quality can impact adjacent waterways and groundwater both onsite and offsite. 
This degradation reduces the ability of these resources to support aquatic life and water for human and animal consumption. 
Nitrates, which are commonly associated with fertilizers and agricultural waste runoff, can seep into groundwater. 
Well water contaminated with nitrates is hazardous to humans, particularly for infants, as it results in oxygen depletion in the blood. 
As alluded to above, proper waste management can reduce operating costs associated with fertilizer application if managed properly.

7. Animal Waste management is Controlling:
Odors
dust
flies
rodents
other nuisances

8. Factors in Animal Waste Management:
Size of operation
climate
type of animal
amount of money to invest
direction of wind
temperature

9. Confined system: Animal are kept in a barn or on a lot
System requires high waste maintenance
Labor or machines required to remove waste
Waste is kept in a lagoon or spread directly on to the field

10. Un-Confined System: Utilizes pasture Waste is left on pasture
Uses little barn space
very low maintenance for animal waste removal

11. Manure as a chemical supplement:
Chemical fertilizers are expensive today
Manure is a supplement for chemical fertilizer
Cheaper
More environmentally friendly
