The Air Management Practices Assessment Tool has put odor solutions at your finger tips.
Using the assessment tool is simple. First, you need to access the Web site at www.extension.iastate.edu/airquality/practices/homepage.html or you can go to the National Pork Board’s homepage at www.pork.org, then go to “Pork Science/Environment.”
Once you have logged on to the site, you can select the emission that you want to investigate. This could include hydrogen sulfide, ammonia, dust (particulates) and odor. Simply click on the appropriate box. This will bring you to a page that outlines options that are available for each type of emission.
Within each type of gas, emission sources are categorized as liquid or solid manure. The charts will lead you to information on air-management practices as it relates to animal housing, manure storage and land application. Each option contains information on the practice, how the practice reduces or controls each emission, an effectiveness rating for the control and relative cost of applying the control practice. The cost includes everything from capital costs to per-head costs.
Here’s an example of how the Web site works.
You can choose permeable covers as a liquid-manure-storage practice to manage ammonia emissions. There’s a linked page that provides more information about permeable covers, including general features of the practices, pros and cons of implementing them and a list of resources for additional information.
The Web site contains only peer-reviewed data, points out Wendy Powers,
“Pork producers need strategies that are readily available to implement because we may see more air regulations come into place in the future,” says Powers. “This Web tool will allow them to see where they can potentially control odors in their current operation, or if they are planning to expand.”
So, exploring air-quality solutions is just a click away. This tool gives you another way to be proactive in improving the air quality in and around your operation.
