Experiences with 7 years of acidification in Denmark - SyreN system, a commercial method to fertilize with sulphate while reducing animal slurry ammonia emission
Abstract In 2009 a group of companies were assembled (Aarhus University, SEGES, BioCover A/S and Grundfos ) and committed to a joint development project “SyreN” - technology for field acidification of slurry, with support from the Danish ministry for development and innovation. The group defined and created a demand specification for using sulfuric acid together with a slurry tanker ...

EPA proposal to change reporting of hazardous substances from farm animal waste
EPA has proposed a rule change to provide an administrative reporting exemption for air releases of hazardous substances -- primarily ammonia and hydrogen sulfide -- from animal waste at farms. The aim is to enable authorities to better focus their attention on hazardous substance releases that require emergency response while reducing reporting burdens on America’s farms. EPA’s proposed rule ...

An integrated perspective on assessing agricultural air quality
The biogeochemical cycling of trace gases (e.g. nitrogen, sulphur, etc.), and contaminants on local, regional, and global scales is a complex system of emissions, transformations, transport, and deposition. To date, limited, if any, attempt has been made on quantifying and identifying direct emissions of gaseous sulphur compounds from agricultural operations. This represents a major regulatory ...

Sow management: Bongdong trumpets stellar production - Case Study
The past decade has seen changes in the South Korean pig industry landscape. From more than 12,000 pig farms in 2005, the number declined to 6,000 in 2012. Despite this, total pig inventory in the country has gone up to almost 10 million heads from roughly nine million heads during the same period, evidence of the growing efficiency and productivity of the country’s pig producers. These ...

A preliminary review of gas-to-particle conversion monitoring and modelling efforts in the USA
Ammonia and inorganic acid gases emitted from livestock and poultry operations, manure treatment, handling and application can affect air quality by the formation of secondary fine particles. The process of gas-to-particle conversion (GTPC) of relatively short-lived gaseous ammonia to more persistent fine particles can affect local and regional air quality far away from the agricultural sources. ...

Seasonal ammonia losses from spray-irrigation with secondary-treated recycled water
This work examines ammonia volatilization associated with agricultural irrigation employing recycled water. Effluent from a secondary wastewater treatment plant was applied using a center pivot irrigation system on a 12 ha agricultural site in Palmdale, California. Irrigation water was captured in shallow pans and ammonia concentrations were quantified in four seasonal events. The average ammonia ...

Manure drying tunnel doing a good job - Case Study
Generating power from renewable energies is becoming increasingly important in Germany as well as on the international level. Thus, it is not surprising that the number of biogas plants is steadily increasing as are wind power plants and solar plants. On the agricultural sector, biogas plants are an additional source of income on many farms besides crop production and livestock husbandry. When ...
