This webpage has been designed to provide you with information on ammonia and best management practices(BMPs) to reduce ammonia emissions from dairies and feedlots. Use the menu on the left to navigate your way through the wealth of information provided. The page will be updated often with new results and information, so check in regularly. If you have any questions, feel free to contact us. Enjoy!
This site is dedicated to bringing you the latest research and knowledge of ammonia best management practices (BMPs) for livestock operations in the state of Colorado. It was created in conjunction with a state wide project entitled On-farm Evaluation and Demonstration of Ammonia Reduction Best Management Practices (BMPs) for Feedlots and Dairies. The objective of our study is to minimize the negative impacts of ammonia on human health and the environment through the adoption of field-tested, effective, and economical BMPs for Colorado’s livestock operations. We have identified the most promising BMPs for dairy and feedlot operations and field tested them at actual livestock operations under "real-world" conditions to see how well they work. We are committed to bringing you only the most efficient, cost effective and practical BMPs available.

Nationally, and in Colorado, agriculture has been estimated as the largest source of atmospheric ammonia, accounting for approximately 60% of the total emissions (livestock is 2/3 and cropping is 1/3 of that total) (1). Ammonia is a concern because it can impact human health, and cause environmental degradation such as changes in vegetation and natural ecosystems, soil acidification, and water eutrofication. In Colorado, Rocky Mountain National Park is a prominent example of the impact of nitrogen deposition from ammonia. In particular, livestock operations, such as dairies and feedlots, have been credited as significant contributors to the increase in N deposition in the Park. However, there are many gaps in the database and assumptions that are being made about the rate of emission from agriculture. Part of this project is to reconcile those gaps and hopefully get a better grasp on the true ammonia emissions from dairy and feedlot operations.
*It is important to note that not all BMPs are viable on every operation. BMPs must be selected individually for an operation based on current management practices, BMPs already in place, operation layout, economics, and ammonia reduction goals. Additionally, the BMP with the most proven potential for ammonia reduction might not exhibit the same results on every operation. BMPs should be chosen wisely and monitored for effectiveness on a continuous basis. This website is a resource to help producers choose the BMPs appropriate for their dairy or feedlot.*
