Evaluation of current products for use in deep pit swine manure storage structures for mitigation of odors and reduction of NH3, H2S, and VOC emissions from stored swine manure

The main purpose of this research project is an evaluation of the current products available in the open marketplace for using in deep pit swine manure structure as to their effectiveness in mitigation of odors and reduction of hydrogen sulfide (H2S), ammonia (NH3), 11 odorous volatile organic compounds (VOCs) and greenhouse gas (CO2, methane and nitrous oxide) emissions from stored swine manure.…

On-Farm Field Days as a Tool to Demonstrate Agricultural Waste Management Practices and Educate Producers

Abstract

Teaching Best Management Practices (BMP) or introducing new agricultural waste management practices to livestock producers and farmers is a challenge. This poster describes a series of on-farm field days designed to deliver information and demonstrate on-site several waste management techniques, most of them well established in other parts of the country but sparsely used in Idaho.…

Abstract

Little information is currently available concerning odor emissions following land application of beef cattle manure. This study was conducted to measure the effects of diet, tillage, and time following land application of beef cattle manure on the emission of volatile organic compounds (VOC).…

Inhibition Of Total Gas Production, Methane, Hydrogen Sulfide, And Sulfate-Reducing Bacteria From In Vitro Stored Swine Manure Using Condensed Tannins

Abstract

Management practices from large-scale swine production facilities have resulted in the increased collection and storage of manure for off-season fertilization use.  Odor produced during storage has increased the tension among rural neighbors and among urban and rural residents, and greenhouse gas emissions may contribute to climate change. …

Vegetative Environmental Buffers (VEBs) for Mitigating Air Emissions from Livestock Facilities: A Review

Waste to Worth: Spreading science and solutions logoWaste to Worth home | More proceedings….

Abstract

Air emissions from livestock facilities are receiving increasing attention because of concerns related to nuisance, health and upcoming air quality regulations. Vegetative buffers have been proposed as a potential cost effective mitigation strategy to reduce dust, odor and other air pollutants from farm and can be an important part of air quality management plan.…

Why Is It Important for Industry and Regulators to Work Together?

The community in the Yakima Region of Washington State has raised concerns over the potential adverse effects of air emissions from dairy operations. To address these concerns, the Yakima Regional Clean Air Agency (YRCAA) proposed a policy process in October 2010 to control and mitigate emissions through implementation of site-specific best management practices (BMPs) on dairy operations.…

Managing Odors, Neighbor Relations, and Estimating Setbacks for Animal Feeding Operations

When a new or expanded animal feeding operation is proposed, air quality and odors are often identified as a concern by community members. Available science-based resources will help you better understand odor, health and zoning issues. Understanding these issues can help community members with diverse interests and perspectives engage in informed conversations as they deal with community decisions regarding zoning and land use related to large animal feeding operations.…
