Lesson 43: Manure Storage

Environmental Stewardship Assessment:

The goal of this assessment is to help you confidentially evaluate environmental issues that relate to outdoor air quality. For each issue listed, indicate the statement that best describes conditions on your farm. If any categories do not apply, leave them blank.

                   

 
1. Relative risk associated with alternative types of manure storage systems

2. Location of storage or lagoon relative to confinement animal housing (Dusty ventilation air moving across storage or lagoon surface picks up and transports additional odors.)

3. Manure surface

4. Agitation during emptying

 
Anaerobic lagoon only

5. Signs of improved treatment for reducing odors… Active lagoons stabilize odors.

6. Permanent pool (or first stage of two-stage lagoon) Size ... Large permanent pools dilute incoming manure and provide a better stabilization of odors.

7. Permanent pool management ...

8. Lagoon loading ... Frequent feeding is preferred to infrequent feeding.

9. Lagoon unloading ... Infrequent pumping causes buildup of salts and ammonia that can become toxic to anaerobic bacteria.

10. Electrical conductivity ...

 
Open lot runoff holding pond/Settling basins/Filter strips

11. Holding pond unloading

12. Draining of settling basins or channels

13. Drainage of open channels for transporting runoff

 
Solid Manure

14. Stockpiling

15. Composting
