Hydrogen Sulfide, How Serious an Outdoor Air Quality Concern

Hydrogen sulfide gas (H2S) is produced from animal manures under anaerobic conditions. Hydrogen sulfide is an odorant and is known as an indoor air pollutant where it can reach toxic, and even lethal, concentrations. But is it more than just an odorant at normal outdoor concentrations? This presentation was originally broadcast on September 19, 2008. More… Continue reading “Hydrogen Sulfide, How Serious an Outdoor Air Quality Concern”

Ethanol Co-Products Impact on Manure Nutrient Management Webcast

The rapidly expanding ethanol industry is producing increasing amounts of corn co-products that will be used in livestock and poultry diets. Inclusion of distillers grains and corn gluten feed in diets alter excretion of nitrogen and phosphorous in manure and therefore impacts nutrient planning. This webcast will explain how feeding ethanol co-products may impact manure nutrient management. The speakers are Joel DeRouchey, Kansas State University who will discuss the impacts for swine and poultry operations. Considerations for beef and dairy operations will be discussed by Galen Erickson, University of Nebraska. This webcast was originally broadcast on February 15, 2008 More… Continue reading “Ethanol Co-Products Impact on Manure Nutrient Management Webcast”
